Moving Libraries to New Disk - Collections there but Empty

Server Version#: 1.24.4.5081
Player Version#:1.34.1.2590-74ea7099 (Windows)

I followed the instructions in the Plex instructions for moving my libraries to another Drive on the same PC:

After this process is complete should all collections, played / unplayed tags, etc be in the new library? In my case they are not. I was moving one library at a time and noticed that that was not the case. The collections were still there but empty. I have a fairly large set of collections. The Played / Unplayed is not that big a problem. This is a small library compared to my Movies Library so did not want to proceed if the issue was going to continue.

Below are some images that show what the screen was before and after (Before removing the “Before” folder (original folder).

Here are the images:

Before Library Addition: Imgur: The magic of the Internet

After Library Addition: Imgur: The magic of the Internet

Before Library Collections: Imgur: The magic of the Internet

After Library Collections: Imgur: The magic of the Internet

I can’t explain why there is one movie in the “After” Collection

Any help on resolving this would be very helpful.

Collections can be like that, i find that you have to be very careful with the underlying media otherwise items drop out of manual collections. I’ve had to rebuild mine a couple of times most recently with the big “upgrade”.
