Any thoughts on what TK85 said?

[@TheSysadminChannel]

@@nonope7000 thanks. I replied

[@laurajacobs1000]

Fantastic! Thank you. It's a clear outline of how to proceed.

You deserve more subs. :) Side note - I'm an old hand and the vid shows why I don't like powershell. I know why you showed the script and in large ent, the powershell makes sense, but here, in the instance of changing the IP, the one step in UI is a very complex multi step in powershell. We've changed Windows from the winner that killed other systems with UI, ... into those systems. Thats no reflection on your excellent vid, just on the wider admin in win.. Thanks for the video!

thanks for sharing the content! I'm not a pro but at 04:08 your porshell comandlet is set to do what you mention not to, it's forcing demotion ( -Force:$true )

[@TheSysadminChannel]

It looks like it was added by default but generally don’t want to force like I mentioned in the video.

Great stuff, just started a new sys admin role and one project was to decom 5 dc's don't ask me why there are so many which I thought that was absurd too but that's the deal haha.

[@KLNYC]

do you have a video on how to migrate old DC to a new DC? thx

[@James-sc1lz]

Any idea if there is any risk just shuttinbg down a DC to see if there are issues with ADDS still installed? I can not think of a single reason why this should be an issue. The idea is we leave it down for a few weeks and then bring it back online to perform the demote only. Of course there will be replication issues with the DCs and partners but thats to be expected. It will not be doewn for more than 180 days and when brought back, the DCs will just play catch up. I could remove ADDS and then power them off but I would prefer not to at this stage. I am a subscriber. Excellent channel. Keep up the good work.

Can you please let me know what is - 3, 4 meaning in that command ? I am from India .

[@ierosgr]

You could explain the options of the cli commands. If you mention that they are out there to search for them the answer will be so the procedure in text guides so what is the point of the video to follow blindly .... and upon that you call it best practice? You also checked for the DHCP and DNS roles. The point of the video would be for them to be active and not offline. You are trying to catch the most usecase scenario by other users not the easiest one
