It should be possible. If it doesn't start you need to check logs.
Is there any special trick to copy the database or is it just to move it like it is?

It means that your database is in a locked state. Usually it means that you stopped service during schema check/upgrade. It has been discussed on forum several times.
Is it possible to move device, account, and log from a windows installation to a Raspberry pi installation?
I have tried to copy and move the database in to the new installation but then Traccar wont start up.
Please give me a hint.
By the way, thanks for an extremely stable software. Good work!
