Hello,
Long time Plex user, first time posting. I am trying to transfer the Plex Server from one windows 10 PC to another Windows 10 PC (on the same network). I was following this tutorial, https://support.plex.tv/articles/201370363-move-an-install-to-another-system/ but when it came to claim the server, it looks like a new server was created “T” where the old one is “V” and not available to claim.
Thanks for letting me know that the issue was the registry. I was wondering why the registry entry seamed so empty.
I realized that Plex saves the registry on the CURRENT user,
HKEY_CURRENT_USER\Software\Plex, Inc.\Plex Media Server\
I had installed Plex on a non-admin user account, when you open regedit, it automatically opens it in an admin account and the admin account had a basic registry entry for Plex.
Once I temporarily added admin access to the old PC user account, I was able to copy the registry entry.
