RE: [ActiveDir] NT upgrade

One key point I forgot was the the NetBIOS name of the cloned domains was changed prior to our Win2K upgrade.  Once the lab was one the net, the lab domains had distinct names (both NetBIOS and DNS) as well as separate namespaces.   Diane -----Original Message----- From: Ayers, Diane [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 02, 2002 6:18 PM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] NT upgrade We did the same thing (lab cloned from production) which was initially isolated but we slowly cracked open the blocks we had on our lab from our production WAN with no "ill effects".  Our key was that our lab setup has an isolated "namespace" from our production world.  Separate WINS, DNS, etc. and the one setup knows nothing of the other setup and vice versa.  A device that can talk to one setup will not be authenticated or validated by the other.   We've had this up for about a year now with no problemos.  Again the key is to kept you name spaces isolated.   Diane -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Hayes, Shawn Sent: Thursday, May 02, 2002 9:55 AM To: [EMAIL PROTECTED] Subject: RE: [ActiveDir] NT upgrade This will work as long as you are on two separate physical networks.  In other words you machines from the two domains cannot and will not be able to communicate - separate hubs, switches, router etc...... The two domains can never exist on the same physical wire plant or like David says you will create a living nightmare.    This is how I tested our upgrade to AD.   NT4 BDC brought online synchronized the domain took the BDC offline and moved it to an isolated lab. Promoted it to a PDC - all user accounts etc were intact Upgraded it to W2K and AD   We then had a fully functional test domain that mimicked the production domain.  We then added E2K servers, print servers etc until we became comfortable with W2K and formulated and documented a plan for production migration.   The point I am drilling in is isolated lab area for testing, do not do this on the same physical plant!   Shawn Hayes   -----Original Message----- From: David Abbishaw [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 02, 2002 12:32 PM To: [EMAIL PROTECTED] Subject: Re: [ActiveDir] NT upgrade Nope,  the domain sids will be the same,  just the descriptive names will change and you'll have all manor of problems. ----- Original Message ----- From: Brian Pietrewicz To: [EMAIL PROTECTED] Sent: Thursday, May 02, 2002 4:27 PM Subject: [ActiveDir] NT upgrade Hello everyone,   I would like to test a domain that has been upgraded from NT to 2000.  If I upgrade an NT domain (domain1) to a 2000 domain and name it domain2, will the NT domain remain functional?  In the end I would like to upgrade an NT domain to a 2000 domain and have both online and functional.   I plan to do this by taking an NT BDC offline, promote it to a PDC, upgrade it to 2000, then name it domain2, and bring it back online.  Will this work?   Can anyone see any potential problems?   Thanks,   Brian
