Prefect Community

Hey guys, I've upgraded from prefect orion `2.0a9` to `2.0a12`. When I try run the server `prefect orion start` it throws this error:
```sqlalchemy.exc.OperationalError: (sqlite3.OperationalError) table flow already exists```
how do I get around this?

Try:
```prefect orion database reset```
This page explains it more: <https://orion-docs.prefect.io/getting-started/installation/#upgrading-the-database>

"Resetting the database with the CLI command `prefect orion database reset` is not compatible a database from 2.0a9 or earlier. Instead, delete the database file `~/.prefect/orion.db` "

Deleting the database manually worked
