Question about upgrading.

[Farokh Irani <farokh@xxxxxxxxxxxxxxx>]

Right now we're running 3.1.6 and I'd like to upgrade to 3.1.12.2. What 
I'd like to do is to save the current version of squid, just in case. 
What do I need to save? I'm running on Ubuntu, and the only version that 
I can (apparently) get using aptitude is 3.0.STABLE19-1ubuntu0.1, so I 
can't use that to just get 3.1.6, which was installed as part of another 
pkg.

So, I'd like to archive the current version so I can put it back up is I 
run into a problem.

Thanks.
