We are about 70% the way along in our Exchange 2003 to 2010 migration, and have had to stop because of extremely rapid database growth on the 2010 side, and we're not sure what is causing it to grow so fast, since we know it is no longer the migration of mailboxes.  but it seems to be growing 3-6GB a day, and we will run out of space soon.  What are some of the things to check?

Thanks!

Hello Rancy - thanks for your response.  I'm not understanding your 2nd part, saying SIS is breaking?  can you elaborate on that?  And how do I check the white space?

thanks

results to that command show 69MB.  The total space used on the volume the DB lives on went down considerably, by 40% last night.  I think the problem was the Exchange backups were not succeeding for several days, which was another issue.  I'm thinking it was logs that were not being committed?  Anyway - we've got plenty of space now.

Sorry - I neglected to get back.  this turned out to be caused by the Exchange backups failing for several days, while actively migrating multiple GBs of mailbox data, causing the logs to grow very quickly.
