Due to an infrastructure change in our environment I'm going to be removing our Exchange 2010 DAG and one mailbox server and I want to ensure that I'm doing it the correct way. I'm going to leave the CAS in place, as recommended by a number of articles I've seen online. Here's the procedure I've come up with. Am I missing anything?
- Remove-MailboxDatabaseCopy DB01\MailboxSRV2 Confirm:$False
- Remove-MailboxDatabaseCopy DB02\MailboxSRV2 Confirm:$False
- Remove-MailboxDatabaseCopy DB03\MailboxSRV2 Confirm:$False
- Cluster node MailboxSRV1 /forcecleanup
- Cluster node MailboxSRV2 /forcecleanup
- Remove-DatabaseAvailablityGroupServer -Identity DAGGROUP -MailboxServer MailboxSRV1
- Remove-DatabaseAvailablityGroupServer -Identity DAGGROUP -MailboxServer MailboxSRV2
- Remove-DatabaseAvailablityGroup -Identity DAGGROUP -Confirm:$False
- Remove-ClientAccessArray MailboxSRV2.domain.com -Confirm:$False
Then I’ll proceed with the uninstallation of Exchange on the decommissioned server.
