Circular logging question - Exchange
Posted on 2010-08-19
I have a Exchange 2003 BE server with many massively oversized storage groups (300GB+) & I want to migrate my users to my new Exchange 2007 mailbox server which will have more, smaller SG's .
In a test run I tried to move 1000 mailboxes & ended up filling up my logs on Exchange 2003 & crashing the server.
I know I can turn on circualr logging and that should solve the log size issue but I will not have any recovery after my last full backup if something goes wrong. It is also questionable if I can restore such a large SG back onto Exchange 2003.
Is there a better way to do this? I really don't want to move 6000+ mailboxes 100 at a time...
