I am upgrading from 8.08 to 12.04. I restored the server once but didn't have enough memory allocated and it locked up (it has about 800 mailboxes and the restore takes about an hour) so I cut bait and am trying it again. I tried the restore again over the top of the original and got this message:
Deleting old MySQL databases ..
Restore failed : SQL drop database
information_schema failed : Access denied for user 'root'@'localhost' to database 'information_schema'
Any idea why this might have happened and how it can be fixed ? Do I need to delete the old restoration before I try a new one?
