I would like to perform an upgrade from 2.6 to 3.0.
What is the procedure to perform the upgrade?
0) locate the packages suitable for install to your system. or prepare
to build your own squid .... http://wiki.squid-cache.org/SquidFaq has
info there.
1) find the 3.0 release notes:
http://www.squid-cache.org/Versions/v3/3.0/RELEASENOTES.html
2) read section 8 carefully (it does include features in 2.6 despite the
title). Looking for mention of any features or config options you need
to use. If you find one you cant do without, then abort. 3.0 is not a
good upgrade for you.
3) read sections 6 and 7 carefully as well. Make any changes you need to.
Should the existing configuration ...squid/etc files need to be deleted?
No. just altered according to results from the above (#3) checks.
Can a backup be performed to be used to reverse back the configuration if
the new version will not work?
Of course you can if you wish.
If you are lucky you may be able to simply uninstall the new version and
install a replacement old version. Then drop in the config files.
Worst case you might need to run " squid -v " (before doing the upgrade)
to find out where all the libexec (helper binaries) and other files used
by squid are located. The configure options give an idea list what file
names and where. They will also need to be down-graded along with the
config files if you revert to the old version. This is usually automatic
when installing packaged versions.
... or the old build options can be used to rebuild an old version clean.
