You (because of your Samba version) can only demote the DC on the DC 
itself, so just follow the info at the top of the page.

Can I also introduce you to a repo that will ultimately give you the 
latest version of Samba:

http://apt.van-belle.nl/

I would fix DC1, then create a new DC running Debian stretch (this will 
give you Samba 4.5.16), join this to your old DC and once it is working 
correctly, transfer the FSMO roles to it and demote DC1. Upgrade stretch 
to buster (make sure to back everything up) then start to use Louis's repo.
