MME - To O365 from a Resource Forest

HI All.

I've done Migrations using QUest AD Migration Manager, and have recently completed my MMEX 0365 Training.

The training however did not cover migrations from a Resource Forest into O365.

Client already has AAD Sync setup, and AAD Sync has both account forest & Resource forest connections. It Merges the account with the Exchange Mailbox in the resource forest using msExchMasterAccountSID matching with ObjectSID.

My Question, When setting up the MMEX O365 Components, where do I install the Agents ? I Pressume this is in the Resource Forest?

Do I need to add the account forest to the tool as well, and if so where?

Is there any documentation available for the above scenario somewhere?
