samba - Jun 2019 - Question about migration from samba3 to samba4

Hello,
Actually we have pdc with Samba3 for domain and now install Samba4 for migrate
the old samba3. My question is, Is possible make a progressive user migration
and both environments works together  (shared folders, printers, etc).   Or the
unique option is migrate all users from samba3 to samba4  ??

Thanks.

I've done exactly that.

I've had 4 'NT' domains, so i've created a new 'AD'
domain, create
users in new domain, do some tests, migrate PC (and users) to the new
domain (still using the old domain's shares), then, after all that
stuff, migrate shares to the new domain, and finally shut off the old
domains.

All task can easily scripted; i must say that i just had a tool to keep
password in sync, wrapping around 'check user script' (NT) and
'samba-tool user syncpasswords' (AD).

That would probably be the only way to do it, if you 'classicupgrade' 
your PDC to AD it is all or nothing. Once you have classicupgraded your 
old PDC, you must turn it off, you cannot have a PDC in an AD domain 
with the same SID.
