I just purchased a Windows 2003 server box and will be migrating my current exchange server thats on a windows 2000 box to it.  I have no idea where to start and need step by stpe instructions.  I know that its not recommened but my exchange server is going to be my DC as well and I will have to migrate ad users to it as well.  I most concerned about the exchange 2003 server the most.  I have a large mail store to move.  its around 40GB.  This is very important to do this correctly for me.

Install Exchange 2003 in the new windows 2003 box and join the existing exchange 2003. Once joined you have two exchange server in the ESM.
Now start movig resources slowly to the new exchange server in windows 2003 box.

How to move:
This KB will tell you how to.

"Creating another Site Replication Service (SRS) instance" please ignore it as its not applicable in your environment. (its exchange 5.5)


Once all the resources is moved all you need to do is remove the exchange server in the windows 2000 box.

This method will ensure that you have no down time and none of the clients need to be re configured. It will be smooth.

Tip: Have 2 weeks buffer where in you move 100 mailboxes per day or more if you could.
Choose mailboxes as per size. any their usage time.

The whole idea is to slowly transfer resource and make the original exchange 2000 box useless and then remove it.

TIP: once all the resource are moved shut down it for three to four days to ensure that no one looks for it.
Finally if you are not able to remove it using the CD as mentioned , remove it from the ADSIEDIT. .... "delete the server object"
Make sure you have the system state backup before you delete any object from the ADSIEDIT.

Have fun and lets me know if you have any questions.

Its easy...

Right click the "public folder" and use connect to... the present server. Or you could do it from the original/new server. ESM is common and you could connect to any public folder server.


Still... A move to new hardware is usally multple issue , i would suggest that you have new thread.
