migrate mailbox exch5.5 to EXCH2003

By komara69 ·
I'm in process installing a new server running server 2003 and exchange server 2003. My old email server is exchange 5.5 SP4. How do i migrate or move the mail box from exchange 5.5 to exchange server 2003? the new server is in the same organization.

i am facing a very similar issue, although my 5.5 and 2003 are in different organizations/domain/forest etc.

does the hardware on your 5.5 good enough to support 2003? you could do an inplace upgrade

what OS is the 5.5 running on?
you cant upgrade directly to 2003 from 5.5 as far as i know, so you need the intermediate step of upgrading to 2000 (beware your foreign mail connectors...)

but essentially if your 5.5 is running on win2k server, then upgrage 5.5 to 2000 n then upgrade 2000 to 2003.

or you could just move the mailboxes and public folders to the 2003...

i would be interested to hear how this is going for you
