Hi Team, 

 

We are working on AD separation project wherein we will going to have new domain setup and then migrate O365 services (user mailboxes and SharePoint ) for few users from existing tenant to new O365 tenant. Messaging environment is in hybrid with on premise exchange in existing domain. 

Tools we are considering are : ADMT and  BitTitan for Tenant to Tenant. Though I have below draft but identified few below GAPS . Need inputs .  

I understand the below high level steps : 

1. setup new domain . Migrate users from existing to new domain . 

2. Setup Azure AD connect and synch users to new O365 tenant

3. Migrate O365 user mailboxes from existing tenant to new O365 Tenant. 

GAP - Since mailbox migration will take sometime to move to new tenant. What will happen to email access during this time?  

How do we deal with free/busy between the scenario between users in 2 seprate domins with seprate O365 tenant? 

4. Migrate SP to new O365 SP 

Objective is to avoid disruption to users and making migration error free. 

 

Any pointers/or if have any document /article link from MS that would talk about the right sequencing for such migrations will help.

 

Regards
