I ran out of room on the SD card on my raspberry pi 2, so I moved my Application\ Support dir onto an external HD.
I then installed PMS on a larger SD card. I tried updating the etc/default/plexmediaserver.prev file in my new PMS set up to point to my copy of the Application \ Support dirt that is now on my external HD. This didn't seem to effect the Metadata on my server at all. For instance, I have several collections and there are zero showing on the server.
I then tried just replacing the Metadata dir in var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/ dir with the one backed up on my hard drive. Still nothing.
I'm sure I'm doing something silly, just not sure what.
Thanks in advance!
