Help needed with a messy Office 365 migration and company split
Hi mderooij, thanks for the reply. Company 2 are happy to be in Tenant 2 with no AD Sync as they are unsure of their building situation for the next year or so. There are only around 30 users in each company so numbers are not a massive issue it's mainly the logistics of performing a cutover migration for one company while in the middle of, and retaining, a hybrid migration for the other company.
I guess what I'm trying to work out now is: given that I am already half way through a hybrid migration with Company 1 (a hybrid migration which won't be completed now for the next few weeks at least) is it ok to manually do a cutover migration for Company 2 (by manually adding in the necessary info such as the mail.onmicrosoft.com SMTP addresses) while keeping the configuration for the Company 1 hybrid and then at the end simply point the DNS for Company 2 to their O365 tenant and then remove their users from the Exchange server? And would I also need to remove the Azure AD sync for them first or do I do that at the end without it causing issues for the users in the tenant?
Thanks!
