No such tool is needed.
The cache is just a directory structure of filesystem files. As long as
you are not fiddling with the actual content or layout you can move the
whole structure between Squid boxes just fine.

 * Copy them into a new directory on the destination machine.
 * Update squid.conf to use that as a cache_dir
 * reconfigure Squid.

Squid may or may not complain about having to throw duplicates away when
loading. It's up to you whether you ignore that.
