The users and groups are all in the PT database. So just set up a
ptserver along with your fileserver on your Linuxbox. So you will have
the fileserverprocesses, the vlserver and the ptserver configured on
that machine. Then you configure your cell to have both DB servers.
They will sync. Then you take away the old one and unconfigure that.

No. As in DO-NOT-DO-THAT. Pleeeeeeezzzzzeeee migrate to kerberos(5)
instead of making yourself unhappy with a service that is only there
for backwards compatibility. You can set up a KDC quite easily (for
example a Heimdal KDC) and it can IMPORT your ka database (passwords
and all). Or use a Windows AD that you probably have running
somewhere.
