Bit of a quandary.

I need to a) rename a Active Directory Domain and b) upgrade servers to either 2012 R2 or 2016 (heard a few issues with 2019, so that can wait).

Would you rename, then upgrade, or would you upgrade first, then rename?

Background:

The internal domain name is from a previous company (oldcompany.com) that was upgraded over the years from the NT days, so the network is actually quite old.
New company bought all the equipment because the old one went belly up, but continued using domain internally, except for email.

Exchange had been outsourced with new company, so all the clients were pointed to the email hosting company. Old company's email has been offline for a number of years now.

Idea was to be as least disruptive, but that may have been a bad call at the time.

Now I want to fix it all up.

The new has their own web presence under newcompanyinternational.com. I was thinking of just using newcompanyint.com internally, which is actually what the current email points to.

Just trying to get a feel before proceeding.
