Migration from G-Suite to Microsoft 365 for one of the largest Healthcare provider in GCC

Customer is an integrated healthcare service provider with 24 operational hospitals, over 125 health centres, 10,000 employees and medical support services spread across the Middle East, Europe and India. 


The idea to move from Office 365 to G Suite was born out of the need for greater synergy and unification. The Customer used G Suite that didn’t provide structured storage and convenient search for project-related documentation and emails. As a result, employee collaboration and project management were hindered. Also, G Suite didn’t allow integrating its mailboxes and calendars with collaboration tool such as Microsoft Teams, which made internal and external communication. 


Roadmap was set to migrate from GSuite to Office 365 starting with the mailboxes to get extended functionality of the services like Exchange Online and Office 365 Groups for sending emails, sharing files, collaborating on projects, scheduling meetings and more. Customer and Microsoft chose Delphi Consulting as a trusted advisor and migration partner for the transition.  

After assessing customers environment, mapping dependencies with various business units of the customer, we put together a migration plan. Timelines were condensed and Google users needed to migrate in two months’ time. As with any large-scale migration, customer was concerned about the feasibility and support that would immediately follow. Delphi chose to plan and execute the migration with BitTitan several reasons, including estimated speed of migration and the fact that no infrastructure was needed. 

Upon completing the planning stage, Delphi’s team performed test migration of a mailbox with the largest number of items. It helped the team to detect potential issues like missing emails that could come up during migration from G Suite to Office 365. 


Migration to Office 365 allowed the Customer to improve employee communication and collaboration as Exchange Online provided intuitive and convenient email management. It allowed new employees to get access to all the previous email communication on projects belonging to a project team they joined. 

As required by the Customer, the company’s employees could easily schedule meetings using Microsoft Teams. They also could leverage Office 365 Groups to create team collaboration space. This area included a shared Outlook inbox, a shared calendar, or a document library for collaborating on documents and enabled its members to make notes on emails.
