Echange 5.5 Server – Migration to another siteLocked
We currently have 4 Exchange servers (version 5.5 to keep), 3 are member of the same site, but the last one, for historical reasons, belongs to another site.
The goal is to migrate the fourth one to the same site as the others without any impact on the users?community.
I have seen papers/documentation about a MS tool included in the Exchange Resource Kit that could do the migration.
For info, about 1000 mailboxes (database size: 120Gb) are defined on the server.
My questions are:
Does someone already successfully perform (with a comparable configuration) a migration using that tool ?
Is there any vital requirements ?
Is there any fallback solution once the process started ?
Any other tool that does the same job (transparent for the users) ?
