[Samba] Howto test upgrades?

[Klaus Hartnegg]

Hi,

maybe this thread should ask an even more general question:

How are AD-DC admins supposed to test upgrades? If there is more than 
one AD-DC, an upgraded DC which causes problems cannot (must not) be 
restored from backup. This is one of the reasons why I do not want to 
switch to AD. A PDC *can* simply be restored from backup. It is even 
enough to switch back to the previous contents of /usr/local/samba, a 
matter of seconds.

Should we force all clients to use/test the upgraded DC by switching the 
other DCs off, and in case of problems turn the new DC off, the others 
back on, and then wipe the upgraded DC? Is it enough to wipe 
/usr/local/bin, make install, rejoin, copy sysvol?

regards,
Klaus
