[Samba] upgrading samba

[Bill Szkotnicki]

Hi,

I would like to appempt a SAFE upgrade on my samba server. ( Centos 5.2 )
Currently the version is:
# /usr/sbin/smbd -V
Version 3.0.28-1.el5_2.1

There are many users logging on to it and accessing the shares.


The last time I tried this ( quite a while ago )
something broke and we had to re-join many windows machines.

It would be nice to have a strategy for rolling back if something does 
not work.
Where are all of the important files?

Would anyone have any advice, suggestions, indications of what to read, 
etc...?

Thanks, Bill
