Having migrated sites using the move mailbox function previously I'm am pretty confident that I won't need to use a roll back plan however it is obviously important to have one.
I am looking at moving approx 1400 mailboxes from one Exchange 5.5 server in a single site multi server organisation to an Exchange 2003 server in the same site. The ADC is in place using one-way synchronisation and is all functioning quite happily. Message flow etc all appears to be working fine and this really is just a confidence booster migration for the client. My question relates to the options available for rollback should there be major issues the following morning. I have looked at several options which include moving the mailboxes back using the same tool, using exmerge to create a backup however I have not got too far with this as I am having difficulties listing mailboxes (maybe due to AV). Finally if most of the users are having issues to restore the Exchange 5.5 server back to its original state. I wanted to check if anyone had ever had to roll back from a large move mailbox process (taking over 5 hours) and if so how they went about it. Secondly with regard to the Exchange 5.5 restore will I need to restore anything in the AD to update where the users mailboxes are or will the ADC sort this out following the restore (I intend to restore the DIR and PRIV edb files) Your experiences would be welcome even if it is just to confirm my feeling that this is a highly unlikely scenario.
