RE: [ActiveDir] 2000 to 2003 Migrations
hey Joe - just to clarify: I was talking about an inplace-upgrade of the DOMAIN - vs. migration to a new DOMAIN... that was David's main question. Inplace-Upgrading the DCs themselves is a separate discussion. but I know you just read my answer and assumed the later ;-) And I truly doubt that you preferr a fresh forest every time there's a new WinServer-OS and happily migrate all users and applications accross... /Guido -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of joe Sent: Dienstag, 13.

RE: [ActiveDir] 2000 to 2003 Migrations
Ah sorry I wasn't clear. I COMPLETELY agree with keeping the forest. My statement of new installs of 2K3 was for the DCs themselves. You don't need to upgrade a DC to keep the AD for 2K to K3 as you did NT to 2K. You can simply prep and spin up a new DC. Actually that would have been cool for 2K as well but would have added complexity... Let you spin up 2K BDC to see how your AD would look and if you decide to go live with it you promote to PDC and your Domain becomes a 2K domain instead of an NT domain. That way people aren't upgrading NT4 PDCs and praying with a BDC locked up and powered down just in case... joe -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Grillenmeier, Guido Sent: Wednesday, July 14, 2004 4:06 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] 2000 to 2003 Migrations hey Joe - just to clarify: I was talking about an inplace-upgrade of the DOMAIN - vs. migration to a new DOMAIN... that was David's main question.
