Hi,
There’s no real upgrade procedure from SQLite to Postgres. You should actually:
- stop Orthanc SQLite
- copy your storage folder to another location
- start Orthanc Postgres,
- run this script to import your old storage folder: [https://book.orthanc-server.com/users/replication.html#direct-access-to-the-filesystem](https://book.orthanc-server.com/users/replication.html#direct-access-to-the-filesystem)
