Why Migrate Your SharePoint Environment

Modernizing your SharePoint environment isn’t just a technical upgrade, it’s a strategic investment in productivity, collaboration, and growth through Microsoft-centric application development. Whether you’re transitioning from an on-premises deployment, consolidating outdated infrastructure, or preparing for Microsoft 365 adoption, a well-executed migration sets the foundation for a more secure and efficient digital workplace.

Organizations choose to migrate their SharePoint environments for a variety of reasons:

End of Support for Legacy Versions SharePoint 2010 and 2013 are no longer supported by Microsoft, leaving organizations vulnerable to security risks and compliance gaps.
Cloud Adoption & Microsoft 365 Integration Migrating to SharePoint Online unlocks native integration with Microsoft Teams, Power Automate, OneDrive, and more, enabling a unified and mobile-ready experience.
Improved Security & Compliance Modern SharePoint platforms support advanced encryption, conditional access policies, and compliance frameworks like FedRAMP and ITAR, especially critical for public sector and defense contractors migrating to GCC or GCC High.
Cost Efficiency & Infrastructure Reduction Moving away from on-prem hardware and licensing models reduces long-term IT overhead and supports future scalability.
Workflow and Process Modernization Migration opens the door for SharePoint workflow automation, replacing manual processes with Power Automate-based solutions and modern forms.

At i3solutions, we tailor each migration strategy to the destination that’s right for your business – whether that’s SharePoint Online, a newer on-prem version, or a hybrid deployment that balances cloud advantages with on-prem control. Our goal is to help you achieve modernization without disruption while preserving the custom features, metadata, permissions, and compliance controls that keep your business running.

Our team of SharePoint architects and Microsoft platform experts will help you identify the migration path that aligns with your infrastructure, compliance profile, and future growth strategy.

Migration Scenarios We Support

No two SharePoint environments are exactly alike which is why we don’t treat migration as a one-size-fits-all task. i3solutions supports a wide range of SharePoint migration scenarios, from aging on-premise deployments to highly customized hybrid architectures and secure GCC High environments. Whether you’re modernizing infrastructure, consolidating systems, or enabling remote collaboration, we help you make the transition with precision and confidence.

Legacy SharePoint to SharePoint Online Migration

We specialize in migrating from:

SharePoint 2010
SharePoint 2013
SharePoint 2016 or 2019 to SharePoint Online (Microsoft 365), with full preservation of:

Document libraries and version history
Metadata and taxonomy
Workflows (including migration of classic SharePoint Designer and InfoPath-based forms to Power Automate and Power Apps)

Ideal for organizations ready to embrace a fully cloud-based digital workplace.

SharePoint On-Premise to On-Premise Migration

Some enterprises and government entities are not ready, or not permitted, to move to the cloud. For those cases, we offer seamless migrations from older SharePoint versions to newer on-prem environments like SharePoint 2019, including:

In-place or parallel migration strategies
Rebuilding legacy components for compatibility
Support for air-gapped and classified networks

Perfect for regulated industries, federal agencies, or defense contractors requiring on-premise continuity.

Hybrid SharePoint Deployments

We design and support hybrid migration strategies where certain workloads remain on-premise while others move to the cloud. This is common in large enterprises where:

Teams or departments have varying compliance requirements
Remote access and collaboration need to scale quickly
Some customizations are not yet cloud-compatible making this an ideal solution for organizations needing Microsoft-centric agile software development services.

Hybrid migration enables phased modernization while maintaining control over sensitive data.

Third-Party and File Share to SharePoint Migration

We also support migrations from:

Network file shares
Google Workspace
Dropbox
Lotus Notes or custom DMS platforms

Our team maps folder structures, metadata, and permissions to native SharePoint constructs, ensuring minimal disruption and a user-friendly end state.

A strong option for organizations consolidating tools and standardizing on the Microsoft platform.

GCC and GCC High SharePoint Migrations

i3solutions has deep experience helping defense contractors, federal agencies, and cleared organizations migrate SharePoint environments into Microsoft 365 GCC and GCC High while preserving workflows, permissions, and architecture using our SharePoint application development expertise. These projects require:

Compliance with FedRAMP High, ITAR, DFARS, and CUI guidelines
Adjustments for tool limitations (e.g., no ShareGate support in GCC High)
Secure handling of sensitive content and user data

Whatever your starting point, i3solutions will design a migration path that fits your governance model, performance needs, and future roadmap – whether it’s cloud-first, hybrid, or grounded in secure on-premise systems.

Still stuck on SharePoint 2010? You’re not alone – you’re just at risk.
End-of-life platforms expose your organization to compliance gaps, security vulnerabilities, and performance issues. We’ll help you break free from legacy infrastructure and move toward a modern, supported, and secure SharePoint environment.

Our SharePoint Migration Process

A successful SharePoint migration isn’t just about moving content. It’s about modernizing how your organization works. i3solutions follows a proven, phased approach designed to reduce risk, maintain data integrity, and deliver a smooth transition to your target environment – whether that’s SharePoint Online, a hybrid deployment, or a secure on-premise upgrade.

Our team of Microsoft-certified SharePoint consultants, SharePoint developers, and Power Platform experts collaborate closely with your stakeholders to ensure every migration is aligned to your business goals, compliance needs, and future plans for Digital Transformation.

1

Environment Discovery and Assessment

We begin with a full assessment of your existing SharePoint environment and how it works within your broader IT infrastructure:

Site collections, subsites, lists, libraries, and metadata
Workflows, forms, customizations, and third-party integrations
User roles, permissions, and security policies
Dependencies across servers, databases, identity management, and Microsoft 365 services

We assess technical debt and identify what needs to migrate, what should be archived, and what can be modernized. This phase is essential for migrations involving legacy SharePoint environments, disconnected file shares, or unstructured content.

2

Strategic Planning and Roadmapping

We build a tailored migration strategy based on:

Your desired end-state (cloud, hybrid, on-prem)
Business use cases and department needs
Timeline, budget, and compliance considerations

We also define what modernization is needed - such as replacing InfoPath with SharePoint forms development or automating legacy processes using Power Automate. Our team brings deep experience in enterprise SharePoint consulting and application development for Microsoft environments.

3

Pre-Migration Configuration

Before we move any data, we ensure your destination environment is ready:

SharePoint Online tenant configuration or on-prem infrastructure prep
Governance, retention, and permission models
Security controls for GCC or GCC High tenants (if applicable)
Third-party migration tool setup (e.g., ShareGate, Metalogix)

This stage ensures alignment with Microsoft best practices, whether migrating to M365 or upgrading on-prem.

4

Migration Execution

We use a combination of Microsoft-native tools and automated scripts to:

Migrate content, metadata, and version history
Rebuild permissions and group policies
Maintain URL structure and taxonomy where needed
Address dependencies such as workflows, custom code, or web parts

Our team of dedicated SharePoint developers works with minimal disruption to end users, often during off-hours or phased rollouts.

5

Post-Migration Validation and Optimization

We conduct comprehensive validation to ensure:

Content integrity and completeness
Functional workflows and forms
Performance tuning and site structure optimization

We also fine-tune search, navigation, and user experience for the new environment.

We specialize in optimizing new sites for SharePoint intranet development, document management, and department-specific digital workplace solutions.

6

Transition and Knowledge Transfer

Finally, we hand off documentation, conduct admin training, and assist with rollout:

SharePoint admin and Power Platform onboarding
Governance policies and site owner best practices
Optional transition to long-term support or team augmentation

We offer flexible options for SharePoint support services, IT staff augmentation, or U.S.-based SharePoint developer assistance post-launch.

Tools and Technologies We Use for SharePoint Migration

Successful SharePoint migrations require more than strategy. They require the right toolset to ensure accuracy, speed, and scalability. i3solutions leverages a combination of Microsoft-native utilities, trusted third-party platforms, and proprietary scripting to execute efficient, low-risk migrations tailored to your environment.

Our team of Microsoft SharePoint application development experts and workflow automation consultants selects tools based on your infrastructure, destination (cloud, on-prem, hybrid, or GCC High), and data complexity.

Microsoft Tools and Utilities

SharePoint Migration Tool (SPMT)

Ideal for direct migrations to SharePoint Online. Supports document libraries, metadata, and basic site structures.

PowerShell for SharePoint

Used for bulk operations, script automation, and precise control of permissions, site provisioning, and metadata tagging.

Microsoft FastTrack (when eligible)

Available for qualified Microsoft 365 customers, used to accelerate cloud migration under Microsoft’s programmatic guidance.

These tools are well-suited for standardized migrations, especially for organizations already operating in the Microsoft 365 ecosystem.

Trusted Third-Party Platforms

ShareGate

Enables rich migrations from older SharePoint versions with robust control over content mapping, reporting, and scheduling. Often used when modernizing site structures or migrating large libraries.

Metalogix Content Matrix

Supports highly granular migrations and restructuring—ideal for regulated industries with audit requirements.

AvePoint

Offers advanced governance, granular policy control, and hybrid environment support for SharePoint and Microsoft Teams.

These solutions are selected when enterprise-level visibility, scheduling, or customization is required, and are especially effective when working with SharePoint document management solutions or complex legacy builds.

Custom i3solutions Tooling and Automation

Proprietary Migration Scripts and Utilities
For highly specialized scenarios, our development team creates custom tools to fill gaps left by commercial solutions. These may include:

Automated permission mapping for non-standard role structures
Migration of custom-developed SharePoint web parts and legacy apps
Bulk remediation scripts for metadata inconsistencies or taxonomy conflicts
Custom scheduling and rollback scripts for phased deployments

As a Microsoft-centric application development firm, we frequently build tools for clients with unique business logic, high security needs, or highly customized SharePoint environments.

GCC and GCC High Migration Considerations

In GCC and GCC High environments, many commercial migration tools (like ShareGate) are unsupported.
We use a mix of manual scripting, secure import/export methods, and custom tooling aligned with DFARS, ITAR, and FedRAMP High compliance.
Our team is experienced in designing workflows that maintain data integrity, audit history, and user permissions without exposing sensitive content to unsupported environments.

i3solutions is a trusted Microsoft system integrator with experience supporting secure, compliance-driven migrations in both commercial and government cloud deployments.

By combining best-in-class tooling with deep architectural knowledge, we ensure your migration is not only executed correctly – but also sets you up for long-term success across SharePoint (link to new SP page URL), Microsoft 365, and the broader Power Platform.

When downtime isn’t an option, you need more than a tool—you need a team that’s done this before.

We understand that SharePoint is at the center of your daily operations. Our phased migration approach is designed to maintain uptime, preserve user access, and avoid disruptions – so you never have to choose between progress and productivity.

Ensure a Disruption-Free Migration

Complex SharePoint Migration Support

Not every SharePoint migration is straightforward. Organizations often face unique technical, compliance, and structural challenges that require more than off-the-shelf tools or lift-and-shift strategies. i3solutions specializes in solving these complexities through a combination of custom SharePoint development, Microsoft Power Platform integration, and deep architectural insight.

Our team of SharePoint developers, SharePoint consultants, and Microsoft system integration experts can help modernize, rebuild, or restructure legacy features as part of the migration process to ensure a stable, scalable, and future-ready environment.

Common Complexities We Resolve

Custom Workflows and Legacy Forms We replace SharePoint Designer and InfoPath workflows with modern Power Automate flows and custom Microsoft Forms development without losing business logic or functionality.s
Heavily Customized Site Templates or Web Parts When third-party web parts or in-house developed components can’t migrate directly, our SharePoint application development team rebuilds them using SPFx or modern frameworks.
Large Document Libraries and Deep Folder Structures We restructure content using SharePoint document management best practices, ensuring compliance with file path limits, metadata policies, and retention rules.
Cross-Site or Multi-Farm Consolidation We plan and execute phased migrations that consolidate multiple SharePoint farms or site collections into unified, scalable structures with taxonomy standardization and governance alignment.
Permission Mapping and Role Restructuring Our proprietary tools and scripts automate the translation of outdated or inconsistent permission structures into Microsoft 365 group-based access controls or Entra ID-integrated roles.
Metadata Normalization and Content Type Refactoring We clean, consolidate, and restructure metadata for improved searchability, records compliance, and downstream automation using Power Automate or Power BI integrations.

These capabilities make i3solutions a top choice for organizations with non-standard environments or regulatory constraints – especially when engaging in SharePoint modernization or preparing for enterprise-scale automation.
