Following situation at a customer:
- Account and Resource forest
- Office 365 tenant
- Azure AD Connect machine running in Account forest, syncing both directories
- ADFS in Account forest
- Exchange 2010 in Resource forest with Hybrid setup
What we want:
- decommision resource forest/domain and Exhange 2010
- install Exchange 2016 in account forest
- make 2016 the hybrid
I was wondering which steps we had to take. We are now already migrating user to Exchange Online. For a new user we create a user with Linked Mailbox in Resource domain. We ADMT it to the Account forest, we trigger ADSync. A mailuser is made in Office 365 and we iniate a mailbox move.
Then in the resource forest we have a Mail Contact in Ex2010 and a disabled account in AD.
1- How can we get rid off these migrated users?
2- When can we install 2016 in the account forest, can it do any harm when we install it next to Ex 2010 which is in the other forest(ofcourse we have a trust)
3- How to move on from here?
Thanks for your support!
