When you upgrade is it possible to use the existing cache directories created through previous version(squid 3) or you have to rebuild your cache.
Ufs, aufs, and diskd types do not generally need replacing on Squid upgrades. Only do so if there is some obvious failure seen after the restart.
null type is now built-in and default. So removing all cache_dir lines is the same as having one entry of type null.
The only regular issue with cache_dir on Squid upgrades is when changing between 32-bit and 64-bit builds. Even if the Squid version is the same in that one case the cache will likely need erasing and rebuild.
