If both are at least 4.0.x it sould be Ok. Maybe old alphas or betas 
could be problematic in a mix with 4 final.

4.0.5 is already out :-)

Thats how I upgraded from 4.0.1 to 4.0.5:
- Just 'configure/make/make install' to 4.0.4 about 3 weeks ago (I 
skipped the version between).
- Tonight I 'configure/make/make install' to 4.0.5 and run 'samba-tool 
dbcheck --reset-well-known-acls --fix' to fix (reset) all ACLs in the AD 
(I had to run the command twice to fix everything). Andrew worked a lot 
on that during the last time. Now all ACLs are fine and I could remove 
the workaround 'acl:search = no' from smb.conf.
