I'd search the archives here - there is lots of good information available on these types of upgrades.
Basically you're well prepared with moving your Exchange server to a dedicated machine (off of the DC) - usually it's easier to move the DC role, but that's up to you. The important thing is that E2k is not running on a DC, as that would be unsupported with a Win2k3 DC. So now - if you care to do an upgrade which is often done in environments such as yours (and fairly low risk at the same time), you're ready to start. It would be roughly in this order: 1. update the E2k Schema in AD with that of E2k3 this should usually fix the issue with a potential conflict with the Win2k3 schema but you'll want to double check before moving on (see http://support.microsoft.com/kb/314649) 2. update the AD Schema with Win2k3 schema (lots of extra infos in http://support.microsoft.com/default.aspx?scid=kb;en-us;325379) 3. before you update the Win2k DCs with Win2k3, ensure you understand your client environment - if you still have lots of legacy clients, you might want to disable SMB signing and secure channel encryption (all enabled by default in the local Win2k3 policies - for DCs you have to change the default domain controller policy (or better: add another one to the OU) to disable these - see support article above 4. update your DCs - at your count, the order doesn't really matter, but should be - PDC: Creates new security principals - Domain naming master: to add or remove new application partitions - Bridgeheads: Site costing for DFS + KCC / REPL events - GCs: Avoid full sync on partial attribute updates 5. udgrade your E2k servers with E2k3 (often done with new HW + mailbox move => up to you) Lots of other infos in the archives. /Guido -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jonathan Watts Sent: Donnerstag, 11.

I administer a small network (at least small compared to most of your networks I would guess) for a secondary school (K-12 equivalent) in the UK. I have 3 servers, all DC's, all running W2K SP4, and one of those DC's is running E2K. I am planning to upgrade to the latest versions of these during the summer break, and at the same time I plan to move Exchange off the DC onto a new dedicated mail server. I think I have most of my procedure plan in place courtesy of the abundance of stuff from MS, but I was wondering if anyone here knew of any case studies or properly documented procedures for this scenario? Very little, if any, of the MS stuff is the same as our setup and I know that all setups are different, but I wondered if there was a document hidden away that properly reflected my situation. Appreciative of any help Jon ********************** Jonathan Watts Network Admin St Catherine's School ********************** List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
