Your configuration is typical of many. The samba-3 migration facility (net
rpc vampire) should work fine. You should be able to run it against the
local BDC - though I have not tested that.

If you need help just ask. I am writing a follow up book to the
Samba-HOWTO-Collection (The Official Samba-3 HOWTO and Reference Guide)
called "Samba-3 by Example" and will have a chapter in there that will
provide detailed presecriptive guidance on the migration process.

If you like we could use your migration opportunity as the basis for the
case study in the book.
