[Samba] Samba 3 and Samba 4 migration

[Amaru Netapshaak]

Greetings!

I am running a samba 3.0.31 PDC with a flat smbpasswd back-end, 
and am ready to make the jump over to Samba 4 and ldb.

I am planning on running both domains in parallel, while I migrate departments
and users to the new Samba 4 domain.   

The problem is that I have people who will log on to machines on both
domains in various locations, and I want to make sure they have access
to their data on the Samba 3 domain when logged onto Samba 4.   

I was thinking I could use NFS to accomplish this.  Maybe just have their
local samba 4 home directory be mounted via NFS to their actual home
directory on the old DC until all workstations are converted to the Samba 4 domain
and then I'll sync up the data one last time and shut the old one off.

I was hoping there would be a better solution :)  Any ideas?

Thank you!
