Upgrade from Exch2000 Enterprise to Exch2003 Standard

[fs483]

How can we upgrade from exch 2000 Ent to Exch 2003 Std without reinstalling the whole and remounting the DB (if it's even possible) ?

I don't believe you can directly upgrade Advanced to Standard versions.

You could however do the following.

1. You need to run the Exchange 2003 Setup.exe with the /FORESTPREP and /DOMAINPREP switches to extend the AD Schema.

2. Install a new server (can be temporary) running 2003.

3. Move mailboxes to new server.

4. Remove old server and reload as Exchange 2003.

5. Move mailboxes back.

6. Remove temp E2K3 server.

I hope you find this post helpful.

Regards,

Mark
