I'm pretty sure you can go directly from 0.1.0 to 0.6.0, there is no requirement to switch from H2 to Postgres, that was just an example in the migration for people that wanted it.
The change that was relevant was between 0.1.0 and 0.2.0, the database properties were refactored, and even if you are using H2, it will migrate from the old H2 to a new one, so just make sure you follow that guidance... "The 0.2.0 release introduces new database configuration in *nifi-registry.properties* which provides more flexible options. When upgrading from 0.1.0, ensure that *nifi.registry.db.directory* points to the location of the existing H2 database to ensure it is migrated to the new database. Please consult the Database Properties <https://nifi.apache.org/docs/nifi-registry-docs/html/administration-guide.html#database-properties> section of the Admin Guide for further details of these properties."
