Hi, I'm using Exchange 2007 and had most of my mailboxes are currently on a single mail server. I recently built two new mail servers and used CCR. I have 7800+ mailboxes and was told that when I move the mailboxes from the old mail server to the new mail server that this will create a huge amount of additional transaction logs that wouldn't be cleared out until the next backup. We do nightly backup and have 1 TB of free space on our log drive. I can't find anywhere that documents that moving mailboxes from one mail server to another would create additional transaction logs. I could understand the existing transaction logs would follow the mailboxes to the new mail server, but I don't see where it would create new transaction logs? I'm planning on moving only 200-300 mailboxes a night, so this wouldn't happen all at once.
Any clarification would be helpful.
Thanks,
Andrew
