[Samba] Best strategy to move/upgrade Samba 3 PDC to new Samba 4 server

[mathias dufresne]

To test this upgrade process you could copy your PDC system into some VM,
then run that VM in some network not accessible from your real PDC. And as
it is a VM, you can run another VM on same not-accessible network to run
your Samba4 and proceed to your tests.

To copy a system I expect tools are existing but you can also simply mount
each partition of your real PDC in some directory (ex: root FS is on sda2 :
mount /dev/sda2 /mnt && cd /mnt && find . | cpio -o >
/path/with/enough/space/rootfs.cpio).
You proceed for each real mounted partition (ie not /sys, /proc...) and
once in the VM, create partition, expend cpio file, run grub, reboot.

No more reason to be afraid ;)
