[Samba] How to add rfc2307 after a join

[mail at crcomp.net]

An old, standalone Samba 4.1 DC was originally provisioned with
--use-rfc2307. When a new Samba 4.7 DC was joined to the original
domain --option='idmap_ldb:use rfc2307 = yes' was not used.
    How do you correct this oversight? Is it possible to remove the new 
Samba 4.7 from the original domain and then join it to the original 
domain yet again but this time use --option='idmap_ldb:use rfc2307 = yes' ?

Thank you in advance.
