I extended our Schema last week and amazingly, nothing broke. Now, before deploying the first 2K8 DC I am running though this "checklist": http://blogs.technet.com/b/glennl/archive/2009/08/21/w2k3-to-w2k8-active-directory-upgrade-considerations.aspx
In some cases I am going to create an equivalent GPO and turn it on. Eventually all W2K8 equivalent GPO's will be on and we'll know at least when we do stand up the first 2K8 DC it's unlikely a new GPO setting will break things.

Would this work? 1. Power down all DC's 2. Snapshot schema master 3. Power up schema master 4. Extend schema 5. Smoke test a. If there are failures revert to snapshot b. If all checks out OK power up remaining DC's David Lum Systems Engineer // NWEATM Office 503.548.5229 // Cell (voice/text) 503.267.9764 ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected]<mailto:[email protected]> with the body: unsubscribe ntsysadmin ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to [email protected] with the body: unsubscribe ntsysadmin
