He makes much more sense than I do.   :-)   I think the Exchange native thing and NT native thing did most of the confusion. -----Original Message----- From: Ayers, Diane [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 9:03 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Rollback from the big bang I know this isn't the exchange list but you got me going.   The comment "5.5 has to have a mixed somewhere in the forest" has me concerned.  Here's the scenario in a nut shell..   Single master NT 4.0 domain model.   Multiple resource domains @ 4.0 with a single account domain.  The upgrade path so far was bring up an empty forest root (non routable). This is running in native mode.  We then began the upgrade of our accounts domain.  It's currently running in Mixed mode.  Plan is convert the domain to native once we complete the DC replacements.  After going native, we'll begin our migration of the resources in the resource domains to AD.  At the same time we will begin the rollout of exchange 2K and migrate Ex5.5 resources to E2K.  Exchange will run in mixed mode until the migration is complete then exchange will be converted to native mode.  Once the resources in the resource domains are migrated, the resource domains will be retired.   Your comment makes me concerned since we will have no "mixed mode Win2K domains" they will be all native.  We'll still have down level NT 4.0 domains with NTLM trusts but no Win2K mixed mode domains.   Our Migration strategy was given a thumbs up by a "well known" consulting organization hence my confusion...   Diane -----Original Message----- From: Hutchins, Mike [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 5:26 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Rollback from the big bang ok, I have totally screwed this one up...   Yes. E2K has to be in Native, 5.5 has to have a mixed somewhere in the forest..   Ours is still root mixed, all others native.. lol   At least I got that part right.. That'll teach me to drink Corona and dispense advise....   :-) -----Original Message----- From: Ayers, Diane [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 6:13 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Rollback from the big bang I'm assuming he means "one domain in native mode for E2K".  Our situation is that the root is native (empty root) and the production domain is in mixed mode.  Based on the docs I read, the domain that e2K is to be installed into must be in native mode.   If we don't have to be in native mode in our production domain, that's going to save a heela lot of work   Diane -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 5:00 PM To: [EMAIL PROTECTED] Subject: Re: [ActiveDir] Rollback from the big bang Do you mean - Only ONE domain needs to be in mixed mode for E5.5? ----- Original Message ----- From: Hutchins, Mike To: '[EMAIL PROTECTED]' Sent: Tuesday, January 22, 2002 7:37 PM Subject: RE: [ActiveDir] Rollback from the big bang FYI, Only ONE domain needs to be in mixed mode for E2K. We have our root in mixed all child (production) domains in native.. -----Original Message----- From: Ayers, Diane [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 22, 2002 5:33 PM To: [EMAIL PROTECTED] Subject: [ActiveDir] Rollback from the big bang All: We are in the midst of our AD deployment and are looking toward the day we switch from mixed mode to native mode.  We need to do this to move forward with our Exchange 2K rollout.  We're a single forest with an empty forest root and a main domain for all of our other resources. Being an enterprise we have a lot of "unknown applications" out there that we no way of testing against native mode let alone tracking down. We have the "big ones" but the rest....  Anyway, I know the say the switch from mixed to native is a one way track.  Baring that I was thinking about some sort of CYA in case things go south in a real bad way. Does anyone have a creative method for rolling back from the switch to native mode.  I was thinking along the lines of doing a restore of a pre-native directory backup or ??  I know we could probably bring one of our NT 4.0 BDCs back online, promote and rebuild the domain but that would entail redoing all of the Win2K DCs. All MS docs say no way. Ideas or am I wasting thought cycles?
