Should you defrag before migrating to E2K

[Tim Rodgers]

Does the migration from Exchange 5.5 to Exchange 2000 present an ideal opportunity to do an offline defragmentation of the Information Store? I was playing with an offline defrag of our IS and managed to reduce it from 68Gb to 41Gb.

Is this accepted practice?

Absolutely! We are trying getting in the practice of doing the defrag (eseutil /d) anytime that we are shutting down a store for some kind of maintenance. If you are moving to a new server for your migration, I don't believe that this is going to help much as far as speed goes as the mailbox move does individual items rather than the mailbox aboject as a whole. Mailbox moves take forever. If you can, run a console session on both the old and new server at the same time to cut your mailbox moves in half (just make sure that you selections on each server are unique, if both servers try to move the same mailbox, both move requests (for all mailboxes) will abort.

Hope this helps,
Rick
