Hello, I am trying to find the documentation about the upgrade procedure from OrientDB to H2 while running the v3.69 OSS app version. The Migrating to a new DB page refers to a Legacy method for pre-3.70 page section that says to download the migrator from the Download page where this section says the following:
Still on OrientDB?

If you are currently using OrientDB and looking to migrate to H2 or PostgreSQL, see 3.70.x Downloads (for OrientDB) instead.

Does this mean that the application version must be on v3.70.x to still support the OrientDB to H2 migration? If not, please let me know where I can find the procedure to do this upgrade while on app version 3.69. Thanks!

These are the procedures we followed - Upgrading to 3.71.0+ for Instances Using OrientDB, a Pre-3.70.1 Nexus Repository Version, and Java 8 or 11

The steps are outlined in the above. You’ll have to upgrade to 3.70.3, perform the database migration, and then you can upgrade java and the product further. In our case we performed an upgrade from 3.66 to 3.70.X and then performed the db migration to h2. After that had been running for several weeks we upgraded to 3.72.0-04 and Java 17.
