Error 500 after migrating to new DSM NAS

[Neobond]

I tried to be lazy and copy the /docker/heimdall directory folders and files to the new NAS and I rebuilt it using compose in Docker Manager but I am getting the Server 500 error whenever I try to add new apps. (I can edit existing ones).

I think the best thing to do is to start from scratch with a new install, but is there a way to save my current database of apps? I looked in the docker/heimdall folders but nothing there seems obvious as to what the database should be.

So, what would I save to restore my applist on a brand new Heimdall docker container?

Thanks in advance.

PS: I am not sure if the Server 500 errors are to do with a version mismatch. I installed it on the old server in September and had WATCHTOWER running, so I do not know if it updated or not. (I stopped using WATCHTOWER on the new server, and will just pull newer images manually).

nm I figured I out, it is the export setting in Settings that has all the apps listed.
