samba - Jan 2021 - Domain SID

When moving from a classic domain to a Samba AD, I think it wise to 
follow Rowland's logic and provision a new domain to avoid all the GID 
issues.? UID's don't appear to be a problem, as they already exist in 
the recommended range.? However, I don't really want to copy all the 
local profiles to what Windows thinks are new domain users due to the 
new SID.? So, is there a way to get the best of both worlds and set the 
SID during provisioning or change it later?

Since I suspect the answer will be NO, is there a way around copying 
local profiles?

Thanks,
Dale

I had no serious issues doing a couple of classic upgrades so I don't
think it's something to fear.
However I have wondered about doing a new provision with a small
number of network users and setting the domain-sid to be identical, as
well as setting the user sid's identically when adding the users. Not
sure if anyone has tried this but it seems on paper that it should
work and the previous classic domain users should get their previous
profiles when logging on.
