Note that if you need only mailbox migration, you should order IMAP migration from G Suite to Office 365.

This migration occurs with the help of a special utility that allows to move any amounts of mail data, calendars, and other information in the shortest time, avoiding possible errors during manual data transfer.

Our objective is to provide a plan and design a way to migrate to Office 365 including email, contacts, calendars, tasks, files, and data. The project will be considered successful when all user data is fully migrated from Gmail and Google Drive to the Office 365 tenant.

IT Partner responsibilities

  1. Gather information and verify the original G Suite
  2. Configure the destination Office 365 tenant
  3. Create and configure users
  4. License assignment
  5. Create and configure a migration plan
  6. Provide informational messages for users
  7. Start and control the data migration process
  8. Provide a OneDrive (SharePoint) profile for each user being migrated

Client responsibilities

  1. Coordinate Client resources and staff schedules
  2. Provide a dedicated point of contact responsible for working with IT Partner and coordinate any outside vendor resources and schedules
  3. Review and approve engagement deliverables in a timely manner
  4. Configure all network equipment such as load balancers, routers, firewalls, and switches
  5. Perform changes to internal and external DNS, as required
  6. Assist with identification of high-risk users (top executives and VIP-users, users with 50 GB mailboxes or larger and/or 30 GB deleted folders or larger)
  7. Ensure IMAP Access is enabled for all users
  8. Ensure contact and calendar services are turned on for all users
  9. Users should not modify any documents in their Google Drive accounts during the migration, because any modifications will not be included in the migration.
  10. End user support

Additional cost items not provided by the project:

  1. Customer team training (could be added as additional service).
  2. Corporate documents migration to SharePoint Online (could be added as additional service)
  3. Desktop software settings

Here are some limitations to be aware of:

  1. SharePoint Online and OneDrive for Business have a limitation in file path length and file names. These limitations may cause issues during the migration from Google Drive. We may implement automatic solutions that can minimize such issues, but preparation is still an important part of the process
  2. The actual maximum of file path length within OneDrive for Business is 260 characters. However, library names, and usernames are included in that limit, so the actual file path could be much smaller than 260 characters long. Also, certain characters need to be encoded and reduce the available size even more
  3. File/folder name extension limitation
  4. There is a list of file extensions that are not allowed to be created inside of SharePoint Online and OneDrive for Business

Upon completion of the project, we will provide a project closeout report. This document will indicate the final project status including acceptance criteria matching, outstanding issues, and the final budget. If you require more extensive documentation, it can be provided for an additional fee.
