Hi everyone.
I have a scenario where I need to migrate approx. 30,000 linked mailboxes to office 365.
Below is the scenario...
I have two forest. Forest A and Forest B.
Forest A have all user accounts
Forest B have all Linked mailboxes and exchange server configured with mixed set of exchange 2010 & 2013.
Now, I want to directly migrate all linked mailboxes to single Office 365 tenant without converting them first to user mailbox in forest A. also, I want to configure a hybrid deployment with this.
I have also gone through some articles saying that multi forest migration is supported by using AADsync/DIRsync utility by setting up some filtering options.
I just want to know that if linked mailbox migration to office 365 and setting up the hybrid deployment with this is possible?
Is it officially supported from Microsoft?
Any help is greatly appreciated.
Thanks
Sandeep Tiwari. (Sandy)
