Migrating hold from exchange onprem to exchange online
I have a question with Exchange on-prem (2016) to Exchange online migration with respect to In place hold and discovery. Let us assume that there are 10 mailboxes in hold (Compliance management > In-Place eDiscovery & Hold) in on-prem. The user is planning to migrate the mailboxes in a phased manner. If 5 out of 10 mailboxes are migrated first, would that create a new hold in Exch Online EAC (Compliance management > In-Place eDiscovery & Hold) for these 5 mailboxes? When the next set of 5 mailboxes gets migrated, would it get added to the above created hold automatically or will it create a new hold?
