When to run those changes:

If the schema change is backwards compatible (is compatible with the current code deployed and can be performed at any time now)
* It is backwards and forward compatible
If the schema change has been tested already on some of the test/beta wikis. Usually, as a last test, change should be applied to testwiki first.
