jassyca -> RE: upgrading to Exchange 2007 (2.Jul.2008 3:33:10 PM)

Have you seen the paper on this site about "Transitioning from Exchange 2000/2003 to Exchange 2007" by Henrik Walther? Here's a link to part 1 of 3:
http://www.msexchange.org/tutorials/Transitioning-Exchange-2000-2003-Exchange-Server-2007-Part1.html
It's a very good guide. But remember, it's just a guide. You may have to make some adjustments based on your environment. For instance, we had keep an Exchange 2003 server for the Lotus Notes connector (yes, there's one that's in Beta for Ex2007 but we don't use beta-ware in production). So there were some steps we had to miss or completely change for our upgrade. You may have to do the same.
Read it and think about how your Exchange server is used currently. And document, document, document as much as you can how your Ex2003 server is configured. If you "inherited" your Exchange server, you might find out some things you didn't know about it. Look at the virtual SMTP service, open every screen that you can and see what it says. Look at your connectors. Do you have any other than just the "Internet" connector? If so, how are they configured and how is the internet connector configured? Does it send messages out directly using MX records or does it use a smart host? What restrictions does it have, what about time outs, etc.? Then look at your info stores. Are there any limits and what are they? How about your recipient policies? There's a ton of stuff to look at.
When I "document" a server's configuration, I usually just take screen shots of the configuration screens, if I can. It's quick and a picture says a 1,000 words. I'll put the screen shots into a Word doc file, one for each "thing" that I'm documenting. So I might have one with 7 screen shots for the various configuration screens of the Internet connector. And another Word doc with 10 screen shots of the Lotus Notes connector. Each in it's own doc. That way, I don't have to dig through a 500 page document looking for the one screen shot I need to see to remind myself of the name of the mailbox we used on the Notes server for our old Notes connector.
But, mostly, take a look at the guide in the above link. And save yourself a whooooole lot of heartache. [:D]
