I'm preparing to update the schema for an Exchange 2010 install. I have to go through a change control process and the question came up of what happens if schema update fails and corrupts the schema. Would active directory suddenly stop working? Would people still be able to authenticate but no new objects could be added or objects modified?
Also how does the schema update process work? I've read something on the forum somewhere here that basically if the update process fails during the update none of the changes prior to failure are committed to the schema? Is that correct?
I've done schema updates for years and never had a problem and I'm aware of having to do a forest recover if something were to really go wrong. It's just those that have to approve the change are afraid of their own shadows. :)
Thanks.
