Hi Rowland

Indeed, this was suggested but was frowned upon, as there are bugs?

Yes, and I believe it could potentially **** up the existing DC2 and any machines attached to it, meaning you have to join every single machine on the network domain again.

Yes, hindsight is a wonderful thing :)

The whole Domain Controller thing on this network is a tale of "suck it and see" and then "if it ain't broke don't fix it."

It was done in the early days of Samba 4 when there was only the git version, and so I thought it would be best to stick with that method for DC2.

So far, they have worked flawlessly for a year, but now the boss wants to cut down the heat generating boxes which are in the server room.


So, I will...

* P2V my Gentoo DC1 exactly as is.
* P2V my Ubuntu DC2 exactly as it.

...and be done with it.

That sound OK?

For now.
