Some of my old notes on schema extension process: http://blogs.dirteam.com/blogs/tomek/archive/2006/02/09/exending-schema.aspx
There is also a showcase from MS IT on that topic, links are here: http://technet.microsoft.com/en-us/library/bb687810.aspx
Regarding backup ... System state backup of course will be helpfull but to roll back schema extension process in unlikely case that something will go wrong be prepared for Forest recovery and planning document for that was just updated by Microsoft:

| Since all the changes have to happen on the schema master, it's rather six-of-one or a half-dozen of the other. If you are bandwidth constrained, I'd do the Exchange update off-hours, because it's fairly large. SCCM isn't as big.

| DCs will only replicate with other DCs running on the same schema version (with the exception of replicating the new schema objects and attributes).
Introducing 3 new schema updates rapidly may create an interesting scenario of having 4 different schemas on the domain simultaneously.

| Let's be clear - there are no 'technical' reasons. That's not to say there are no 'political' or 'cultural' reasons.
Surely as a consultant, you tailor your solution to meet the needs of the client J i.e. you have no 'personal' preference per se :->

DCs will only replicate with other DCs running on the same schema version (with the exception of replicating the new schema objects and attributes).
Introducing 3 new schema updates rapidly may create an interesting scenario of having 4 different schemas on the domain simultaneously.
Not sure of the worst case scenario in this event...

Since all the changes have to happen on the schema master, it's rather six-of-one or a half-dozen of the other. If you are bandwidth constrained, I'd do the Exchange update off-hours, because it's fairly large. SCCM isn't as big.

| Hi Brian
We tend to use the 'peel off' method as most often we have more than one schema update to lay down, as we tend to lump them in as downtime can be tough to get in some environments.

All you're doing is creating a scenario where you apply the update to the schema master holder and then let it sit there. It's not doing anything or remotely acting like a normal DC given you've got it off the wire/isolated. Thus all you're doing is pushing the appearance of some possible problem off in to the future when you plug the box back in and let it replicate with the environment. No win if you ask me.

| We do isolate our schema master when performing updates to the schema, but the only reason we do this is to appease Change Management.
There's almost no *technical* reason we do this--we acknowledge that all we can do with an isolated schema master is validate that the extension process added the correct attributes and classes as documented. There is absolutely no way for us to be sure that this new schema won't cause a problem with a production system once we hook the master back up and it replicates.
Sure, we drive our schema through lower environments first, but these environments do not contain 100% of our business applications (and this is something we've been unable to change due to politics). So in our environment, there's always a slim chance that a schema extension will muck some app that hasn't seen the schema in a lower environment, and isolating the schema master does nothing to help this.

| What about the "take a DC offline and use it as a new starting point if things go wrong" approach. I know its probably only practical for small organizations. Also by the time you find the problem you will probably have made so many updates you don't want to go back, but I think that's all you can do.
Really the thing about the change process is that it should :-
1) Assess the risk and recognise that whilst the change is risky and hard to back out its also un-avoidable, 2) Put in place resources and procedures to deal with the fall out should there be problems.
Often IMHE it picks up on "1" but then doesn't understand it needs to implement "2" and instead gets into a flap.

Hi
So, make the management happy by doing something we all know is a check in the box; value - not much as the Schema Master will more than likely very happy with the schema changes in isolation. The process makes sense because they (management) need to approve the approach (change/risk) to the solution - although the approach is merely smoke and mirrors and a tranquilite to potential failure which we have all had to adapt to without knowing the real exposure of the risk (probability x impact).
Would the mitigation be to ensure there is a backup in place to authoritatively restore the schema?
I love SCCM (although a completely different topic/technology but bears resemblance in the limitations in the realistic feasibility of fully testing AD changes) in the way you can progress through an iterative change cycle in a very controlled manner. i.e. Pilot Collection - one Computer - test for success > add a bunch of different computers > test for success etc etc. It provides a very easy and somewhat grey transition moving from piloting to production while limiting the scope of exposure significantly.
The scenario of taking the Schema Master offline is neither a Pilot, POC or a Test. It is a test to see if the schema accepts changes. Naturally, it will if you have schema admin rights...

Yeah, I've never seen a test environment that's perfect (ours is considerably less-than...) so there's always that minimal risk. Over the years we've done a good job of debunking a lot of the fear that management had with the schema extensions. One thing we've never been able to do is convince them that it doesn't necessarily buy you anything to isolate the schema master during an upgrade.
And like Brian said, it's almost not worth the energy. Isolating adds a few commands to the process. I'll happily deal with that rather than ripping more hair out trying to change somebody's mind

Been there, done that. The schema change broke the single-signon the some unix systems were using (they detected the latest SFU attributes and auto-magically started using them - and those attributes had no data in them).
Did we test unix SSO? Sure did - with the unix support group driving the test from their dev machine.
Did the test work? It did - on the dev test machine.
The key question became:
Did we test *every* version of unix/linux/*nix with the different versions of the SSO code on the unix boxes? No - too many versions.

So if I understand, you'd rather rebuild the entire forest than add some additional checks earlier in the process?
The scenario of taking the Schema Master offline is neither a Pilot, POC or a Test. It is a test to see if the schema accepts changes. Naturally, it will if you have schema admin rights...
Perhaps u miss the point - the change will be 'accepted' of course but will it be applied 'successfully'? Two [subtly] different considerations and the 'SM offline' approach assists with the assessment of the latter.

Been there, done that. The schema change broke the single-signon the some unix systems were using (they detected the latest SFU attributes and auto-magically started using them - and those attributes had no data in them).
Did we test unix SSO? Sure did - with the unix support group driving the test from their dev machine.
Did the test work? It did - on the dev test machine.
The key question became:
Did we test *every* version of unix/linux/*nix with the different versions of the SSO code on the unix boxes? No - too many versions.

| Confirmed! I can run 32-bit Exchange 2007 SP2 version to extend AD & *"If your Active Directory environment is currently Exchange 2003 and you are upgrading to Exchange 2007, then when you extend the schema, the schema changes included with Exchange 2007 through Exchange 2010 will be deployed in your environment" :*
32-Bit vs. 64-Bit Version of Exchange 2007 Exchange 2007 RTM and SP1 are available in two platform versions: the 64-bit version is for live production environments and the 32-bit version is for non-production environments (such as labs, training facilities, demos, and evaluation environments). Only the 64-bit version can be purchased because you cannot run 32-bit Exchange 2007 servers in production. There are exceptions with respect to production and non-production use of the 32-bit platform because Microsoft does allow minimal supported use of the 32-bit version in production environments: You can use the 32-bit version in production to extend your Active Directory directory service schema. For detailed steps about how to prepare Active Directory for Exchange 2007, see How to Prepare Active Directory and Domains. http://technet.microsoft.com/en-us/library/bb125224(EXCHG.80).aspx<http://technet.microsoft.com/en-us/library/bb125224(EXCHG.80).aspx>
still working on lab thanks!
