First, make sure Squid is not running.

Assuming that your 'mv' can move directories between filesystems
(most can), you can just do:

    # mv /from/oldcachedir /to/newcachedir

then update cache_dir in squid.conf and restart.

This procedure will take a while, depending on the size of your cache
and the speed of your system.

If you don't want to have any interruption of service, and can wait
a really long time (like days or weeks), you can use this trick:

Add a new cache_dir and mark the old cache_dir as read-only. New
objects will get stored to the new location, and you'll get cache
hits from the old one. After some amount of time, say when the new cache
dir fills up, you can remove the old one.
