Account issues should be addressed before migration rather than during migration itself. Identify unused accounts and mailboxes and delete them rather than migrating them. Note manual items like rules, filters, and distribution groups. As also, ensure that all users have the latest versions of Outlook and that all platforms can connect to Office 365.

A pilot before a big deployment is an excellent idea. Automate to reduce errors and speed up the migration. Network bandwidth influences migration speed. You can gain bandwidth by migrating data at a low-traffic time of day.

Your plans are all geared towards a successful transition. However, having a strategy is essential in case of unforeseen issues. Know how to restore users’ email service on your present system. This recovery process should be part of your pre-migration testing.
