Subject: Schema upgrade/rollback

In this day and age of VM’s, what would be the simplest way to test and 
possibly roll back a schema extension? 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
