[squid-users] Upgrade from 3.1 to 3.3

My problem is the same described in the following link:

I can't access a Sharepoint web page using internet explorer it keeps saying "Unable to Login", for example with Chrome I don’t have this issue but IE is the browser I need to use. My proxy service, whitelist, etc., works with no problem.

I took the example of that bulletin so I decided 3.3. I guess higher versions should have that issue fixed.

Each version you go to over 3.1 has different SSL-Bump design needed.
Other than that the last major pain was the jump to 3.2 when helper renaming happened.

Also, We've done a lot more work over the recent series to make migrating versions a lot less trouble than ever before. So the more recent you go the less total pain will be involved.

We dont have a step-by-step guide. How you do it depends on how you previously installed Squid, what you are using it for, what your abilities are, etc.

In general;

1) make install the newer version over or alongside the old version, but don't run it

2) run "squid -k parse" using the new squid binary and fix anything in squid.conf it labels as FATAL or ERROR. Without these fixed the new Squid will not run.

3) also fix as many of the warnings and other issues it mentions as you can.

4) start the new proxy, and monitor for a while to see if unexpected problems appear

If you have a vendor packaging Squid for you the first step is whatever they require. They should take care of most of the upgrade and you are just left with making sure the config file is updated. Sometimes they take care of that too.

As I mentioned above upgrades crossing Squid-3.2 had their helper binaries renamed. So see the Squid-3.2 release notes for details on what the new names are. You will need to edit squid.conf for those if nothing else.

If you have the time it is usually a good idea to look over the release notes of the new versions you are going to and/or skipping over. We have added a lot of features aimed at making Squid easier to use. You may find you can simplify your systems somewhat.
