Enterprise Vault archives migration / export query
what would your recommendation be for our scenario where we have an existing Enterprise Vault (8) installation currently archiving a domain (1000 mailboxes) which is due to be closed and we have a second domain which all users will be migrated to.
The idea proposed is that we use the Export archive function within EV to restore all items back to the original user mailboxes, then the Exchange Admins will migrate mailboxes / users to the new Domain. A new EV 10 (x64) installation of Enterprise Vault will be setup and all users will be archived
does that sound about right ?
a concern we had was about the hidden message from the previous EV installation within some of the user mailboxes when the new EV will begin archiving - does that need to be removed ? or will the new EV installation replace / delete it with a new hidden message
