Hi, if you try and run them on the same network, I think that you will
have problems, this is taken from the classicupgrade page on the wiki:
Also, it is necessary to do testing on a separate network so that the
old and new domain controllers don't clash. The issues with having both
domains 'live' at the same time are:
* The databases are not syncronised after the initial migration
* Even if no changes are made to the DB, clients which see an AD DC
will no longer honour NT4 system policies
* The new Samba4 PDC and the old DC will both claim to hold the #1b
name as the netbios domain master
This may not be a problem if you do change the workgroup/realm names,
but I do not know enough to be sure. I do know that you can run run 2
different AD DC's on the same network provided that they have different
workgroup/realm names
