Squid is doing the cache format upgrade automatically. The process is a
disk scan identical to if the swap.state journal was corrupted or
missing. It may take some time if you have large cache_dir.

As a workaround you can run squid as a proxy-only for the production
traffic (like your secondary one) and run another with a dummy config
file to do the cache rebuild "offline". Then swap back to normal
configuration with cache when the rebuild has finished.
