Hi all,
I am looking to migrate our exchange to O365 soon.
We currently have our Exchange on-prem and split accross 3 roles (2x CAS, 2xHub, 2x Mailbox servers-1 of which is online archive).. We also have ADFS in sync with FIM.
My question is what would be the best practice for migrating?
I would assume I would need to disable the syncing between ADFS and FIM dduring the migration.
-Would i migrate each mailbox 1st? or by users? (in what way are the archived mailboxes are linked with the user mailboxes?)
we have over 1000 users so would need to be sure this is done correctly..
