Hello.

I have a project to upgrade an Exchange 5.5 server to Exchange 2003 , there are 40 mailboxes which are larger then 6 GB. There will also be a new BES server, I am posting to look for recommendations on the order of steps and the see if anyone can tell me things to look out for.

Should I move users to the new BES first? I know there devices are less then 24 months old. Will reactivation occur OTA, will the users be required to do anything?

(to answer the obvious they plan to stay on Exchange 2003 for a few months before moving to Exchange 2010)

Thanks.

Which is your current and proposed BES version?? Are you going to have new version of BES on new hardware??

Cheers!!
