Cannot start service after upgrade from 0.15.XX to 0.20

[fflorent]

I have upgraded meilisearch from version 0.15.XX to the latest version (0.20.0~ynh1).

I get this error when attempting to start the service:

Error: Cannot open database, expected MeiliSearch engine version: 0.15.XX, current engine version: 0.20.0

Seems like there is a procedure to update from version 0.15 documented here: https://docs.meilisearch.com/create/how_to/updating.html

If you get the error Cannot open database, expected MeiliSearch engine version: 0.X.X, current engine version 0.Y.Y, your database is not compatible with the currently installed MeiliSearch version.

Maybe we should try to dump the database before upgrading: https://docs.meilisearch.com/create/how_to/updating.html#updating-from-v0-15-0-or-above

I am on it!
