Two questions:
1. Did you take the PDC offline, during the PDC upgrading? I know take one
BDC offline just for rollback if something goes wrong.
2. and company.internal which one is better for AD namespace?
which one did you choose? and why?

My upgrading plan almost same as yours. Just some people suggested me to
take company.internal namespace, and take PDC offline during the upgrading
until the machine restarts.
