As I mentioned last time, one of the things to be aware of when running RasPlex for the first time is how very slow the UI is before the cache is built..

With our larger library, it took a few days to cache everything properly.

Note: Based on the speed of development, this is going to be outdated information VERY quickly.

I’ve been doing a bunch of other projects, so now need to update, and want to preserve the cache (of course).

So, since I have to go through the process anyway, it’s sharing time.

  1. ssh in to the Raspberry (default username/password: “plexuser” / “rasplex” (no quotes) )
  2. Transfer the ‘/storage/.plexht’ folder to your local computer
    (I would normally suggest using gzip, but that would involve the tiny CPU, so I personally just transferred the whole folder with rsync. SCP and other SFTP programs are good choices too)
  3. Use the GUI Installer to update RasPlex (which is a nice choice that only means pressing a couple buttons)
  4. Boot up the updated version
  5. Transfer everything back, overwriting the updated ‘/storage/.plexht’ folder

And, a pleasant bonus:

This process keeps the myPlex login info, and all other Plex personalizations.
