There was no database change between 4.2 and 4.3. So it should be OK to
have a mixed DC environment. However keep in mind, that things may have
changed and the 4.3 DC may handle some things different than the 4.2 does.

Just an example: For 4.3 (or was it already in 4.2?) support for a
specific time format in an attribute, Windows terminal servers are using
for storing licence information, was added. The old Samba version
rejected an add/modify on that attribute with an error, while it passes
now on the new one. This could make the TS licencing tools fail if it
talks to a DC running the old version, while it works on the new one.
