A SharePoint Migration Saves Users 20,000+ Hours a Year at a Federal Development Agency

An Unsupported Environment Bills You Every Year

The compliance side of the ledger was the sharpest. A platform Microsoft no longer supports leaves sensitive data vulnerable to unsupported security threats, and the agency could not treat that as deferred maintenance when continuity of operations is what the countries it assists depend on. Staying put meant carrying open compliance risk exposure, in the form of potential audit findings or remediation costs, with no path on the existing platform that would close it. The destination environment carried security features the legacy system did not: data encryption, access controls, and data loss prevention policies.

The operating costs recurred on a fixed schedule too. On-premises hosting, licensing, and maintenance billed every year, and IT teams kept spending hundreds of hours patching and maintaining legacy servers. Those were annual line items paid to keep an unsupported platform alive, and the staff hours spent maintaining it were hours not spent on the agency’s programs. Measurable Outcomes below puts a figure on each of them.

Move Everything, Break Nothing, Finish Quickly

The migration approach had to satisfy several requirements at once: transition to a supported environment while protecting data and content, maintaining security and compliance, minimizing usability impacts on users, preserving functionality and features, and ensuring the migration was completed as quickly as possible. Maximizing server uptime during the move was part of the same constraint. A migration that met four of those five and dropped the fifth would not have been an acceptable outcome for an agency whose continuity of operations was the reason for the project.

The complexity was in the inventory. The existing environment held native SharePoint components, workflows, forms, third-party tools, content, and permission structures, plus customized forms created in InfoPath and a SQL Server backend holding the data. The agency’s data structure and customizations were the specific thing it feared would not transfer. Interactions from many supporting departments had to be considered, and the impact of the transition projected throughout the organization, because user adoption was a stated requirement rather than a hoped-for side effect. The destination was in scope as well as the move: the agency sought to optimize its cloud infrastructure to enhance performance and cost-efficiency throughout the migration process and beyond.

Senior Microsoft Specialists with Proven Delivery Depth

The agency needed an expert IT consultant who could perform discovery and analysis on the current on-premises SharePoint system to determine the best approach for continuity of operations and maximizing server uptime during the migration to Office 365 and a supported SharePoint platform. That is a specific profile: a team fluent in data mapping, custom integration, and user training, able to review every technical asset in a legacy environment and say with confidence what would move cleanly and what needed to be rebuilt around.

The agency engaged i3solutions, a Microsoft Partner with 30 years of delivery experience and 1,500+ Microsoft engagements, delivered by an all-senior, all US-based delivery team. On SharePoint migration specifically, i3solutions brought over 20 years of migration experience and the ability to draw on numerous lessons learned, which is what a detailed migration plan is actually built from. Those lessons showed up at the plan’s edges: the agency’s customized InfoPath forms were treated as a continuity requirement to be integrated, not a legacy artifact to be rebuilt after the cutover.

i3solutions ran the SharePoint migration to a supported SharePoint platform and Office 365: Content Discovery to identify and analyze the existing on-premises environment, data mapping of the agency’s data structure and customizations to the corresponding elements in the destination environment, and ShareGate to move large volumes of content and data.

The toolkit was small and each piece had one job. Content Discovery identified and analyzed the existing on-premises SharePoint environment, including content, document libraries, lists, and permissions, which is what made the complexity of the migration knowable before anything moved. Data Mapping then mapped the agency’s existing data structure and customizations to the corresponding elements in the destination environment, so data integrity was maintained. ShareGate, a third-party migration tool built for SharePoint migrations, moved large volumes of content and data from the old environment, transferring it securely and efficiently with minimal downtime. On the destination side, SharePoint Online provides a modern version of SharePoint with collaboration and document management capabilities, and the agency’s content, sites, and data moved there for its scalability, reliability, and cloud-based features; Office 365 supplies the cloud-powered productivity layer that works alongside SharePoint for day-to-day collaboration. SQL Server remains the backend data storage for the SharePoint environment, essential to data integrity and database connections through the transition. Customized InfoPath forms were not rebuilt: an integration between SharePoint and those forms carried them across intact.

20,000+ Hours Reclaimed Annually

Moving to a supported SharePoint platform and Office 365 saved an estimated 15 minutes per user per day and roughly $500,000 a year in infrastructure cost.

The productivity result is the one that compounds. SharePoint’s modern collaboration features, such as real-time co-authoring and easy sharing of documents, improved collaboration among the agency’s teams, increasing productivity and shortening the path from question to decision. Agency staff save an estimated 15 minutes per user per day. Across hundreds of employees, this equates to more than 20,000 productive hours annually, valued at over $200,000 in efficiency gains. That figure recurs every year the agency stays on the modern platform, and it is paid in the currency the agency actually spends: staff time on international development programs.

Retiring on-premises infrastructure eliminated ~$500,000 per year in hosting, licensing, and maintenance costs, while enabling cloud scalability at no additional capital expense. That is recurring operating cost, not a one-time saving, and it sits alongside a separate and differently shaped item: the compliance exposure of running an unsupported system, which closed with the move rather than continuing to accrue. IT teams reclaimed hundreds of hours previously spent patching and maintaining legacy servers, equivalent to $100,000 annually in reduced IT labor and support overhead. The move itself was not paid for in downtime either: the use of ShareGate automation reduced migration downtime from weeks to just hours, avoiding tens of thousands of dollars in lost staff productivity and maintaining continuity for critical international programs.

Off an Unsupported Platform, onto a Supported One, with the Customizations Intact

The engagement established that leaving an unsupported SharePoint environment does not require accepting the loss of what was built on it. Content Discovery made the legacy environment knowable, data mapping carried the agency’s data structure and customizations element by element into the supported platform, and ShareGate moved large volumes of content and data securely with minimal downtime.

Customized InfoPath forms, existing workflows, and third-party tools kept working after the move. The return landed on both sides of the ledger: staff hours recovered across the agency every year, and on-premises hosting, licensing, maintenance, and patching cost retired along with the servers. Continuity of operations, the thing the agency and the countries it assists depend on, held throughout.
