Migrating old cache server data

Hello!

I'm in the process of installing Cache Server v6 on our server. We are running one of the previous versions (not sure exactly which version number, but from the 2017 era), and I'm wondering if there is any simple way of migraing all that previously cached data into the new cache server? Or is everything stored in the same way, and I can just point the cache server to the same path as previously?
