Ok here's the scenario. Currently in place there is a win2k dc with ad. One the same domain is an Nt 4.0 BDC running exchange 5.5 sp3. I want to upgrade to exchange 2k on the same server that has has exchange 5.5 now. There are sixty mailboxes and about 25gb in the information stare. What to do. I thought of two possible scenarios.
First is to cheat and use exmerge export to psts (or can I without 2k installed) then wipe out the box. Install win2k and then install exchange 2k. Then use exmerge to import the pst's into the boxes.
Second is to do what MS says to do which is to upgrade the existing box to win2k then install the ad connector. After that upgrade exchange 5.5 to exchange 2k.
Has anyone done either of these. Which is better and which is prefer.
Thanks in advanced
