- From v1.6.0 on, Harbor will automatically try to do the migrate the DB schema when it starts, so if you are upgrading from v1.6.0
or above it's not necessary to call the migrator tool to migrate the schema.
- From v1.6.0 on, Harbor migrates DB from MariaDB to PostgreSQL, and combines Harbor, Notary and Clair DB into one.
- For the change in Database schema please refer to [change log](../tools/migration/db/changelog.md).
- Since v1.8.0, the configuration of Harbor has changed to `.yml` file, the migrator will transform the configuration
file from `harbor.cfg` to `harbor.yml`. The command will be a little different to perform this migration, please make sure
you follow the steps below.

please check the log of core to debug.
