Trying to move between 2 servers

May I suggest an alternative? Linux server-server move can be reduced in complexity over what the article states (so vague)

You clone from one to the other. Remember to decommission the original (Preferences.xml) before starting again else the two will collide (UUID’s will be identical)

Presuming new mount points are not the same, You’ll want to integrate this as part of the process.

You will effectively,

  1. Prepare the source system (turn off all automatic library features)
  2. Clone
  3. Decommission source system
  4. Perform media location updates before enabling automatic library features.
  5. Final cleanup when done.
