We are planning migration from MIIS to FIM2010.
We use MIIS for galsync and password sync.
We have already FIM in our domain.
If we import mailbox to FIM metavese , I think there is no side effect if we do not export contacts to each ADs.
We would like to do Join test of existing contact object to avoid contact recreation when migration.
If we import mailbox to metaverse and do join test of exisiting contact to imported metaverse object, how could I avoid negative impact on production environment ?
I though if we uncheck the synchronization target OU which contacts will be created after join test, contacts are disconnected and there will be no effect on production environment ?
