Hello all, I am not able to find what is last version of Nexus 3 which supports H2 and allows migration to PostgreSQL if in future we decide to move to PostgreSQL. Currenlty running 3.77.1-01 Also are there plans for Java 21 maybe ? Tnx

What is last version which allows migration to PostgreSQL from H2?

Surbanoski, Every present version of Nexus Repository that supports H2 also allows migration to Postgres. There are currently no plans to make any version of Nexus Repository the “last” version that supports migration from H2 to Postgres.

H2 is still supported in the current Nexus, while I can’t predict the future today we don’t have plans to remove it.
