MIGRATION OF 750+ USERS FROM EXCHANGE 2013 TO OFFICE 365 ENTERPRISE
The Project was centred on migrating 750+ users from the on-premises Exchange Servers 2013 to the Exchange Online System. This was done ober a period of 3 months as most users had large mailbox databases.
A cutover migration was then done over the final weekend.
Lessons Learned
Advanced filtering options – where we can choose to migrate chosen groups of users and even select to migrate only some of their items, based on a time and folder filter. This lets us migrate only the most recent emails and calendars, switch to Office 365 and then move the older items to the cloud.
No downtime – the migration could run in the background with no impact on users.
