I’m trying to somehow upgrade the docker-based Orient DB installation to H2 so that the latest Nexus3 image can use it. Alas, so far, I’m not having any successes. At a glance it seems the migration jar is simply broken. However, this could also be a case of Java version (I’ve tested this both with 11 and 17). Current logs: ```auto /nexus-data/db_bak $ java -Xmx16G -Xms16G -XX:+UseG1GC -XX:MaxDirectMemorySize=28672M -jar nexus-db-migrator-*.jar --migration_type=h2 15:25:26 [main] WARN c.s.n.d.migrator.MigratorApplication - Please ensure any Nexus Repository instance has been gracefully shut down before proceeding. 15:25:26 [main] INFO c.s.n.d.migrator.MigratorApplication - Do you want to continue [y/n]? y 15:25:28 [main] INFO c.s.n.d.migrator.MigratorApplication - --content_migration parameter is absent.

The documentation is lax on the Java requirements or issues with the migration tool… ---

I’ve managed to resolve this. See [this community answer](http://community.sonatype.com/t/migrating-to-3-71-on-a-docker-based-installation/13045/5).
