I have a Synology 8-bay NAS used for home-lab purposes, but also doubles as local home storage as well.

As part of upgrades, I was decommissioning a volume for a new one with higher capacity drives, however I had Plex installed on the volume to be decommissioned. I moved all the data using the internal file manager, but the package installation remained in place.

Migrate package to another volume

1. Stop your application via the Synology package center UI.
2. Login to Synology using SSH and elevate to root.
3. Use “ls” against /VolumeX/@appstore to find your package folder name
4. Use “mv” to move the data between the old and new volume, you may need to create the @appstore folder first.
5. Remove the symlink from the current volume and create the new symlink to the new volume.
6. Stop and start your package in the Synology Package Centre.

Below is an example the commands I used;

sudo mkdir /volume2/@appstore
sudo mv "/volume1/@appstore/Plex Media Server" "/volume2/@appstore"
sudo rm "/var/packages/Plex Media Server/target"
sudo ln -s "/volume2/@appstore/Plex Media Server" "/var/packages/Plex Media Server/target"

Now when you try to remove the volume, your package will now show as attached to the volume.
