Background：
・We plan to upgrade Sonatype Nexus from version 3.59 to 3.79.
・Since we are migrating from OrientDB, we understand that it is necessary to upgrade to 3.70 first as an intermediate step.
・Due to the requirements for the number of users, we need to migrate to PostgreSQL instead of H2.
・We are currently using an S3 blob store.
・The server in use is running RHEL 8.1.
After upgrading from version 3.70.4 to 3.79.1, migration and startup completed successfully.
However, three types of errors occurred in the nexus.log, and materials in the target blob store are no longer accessible.
The upgrade procedure and error logs are detailed below.
Based on the error content, we believe this is a similar issue to the following:
Questions:
・What is the cause of this error?
・Could you please advise on how to resolve this error?
Upgrade from 3.59 to 3.70.4 (Operation confirmed normal after upgrading to 3.70.4):
Step
Action
1 Stopped Nexus
2 Extracted nexus-3.70.4-02-java8-unix.tar.gz
3 Executed nexus-db-migrator-3.70.4-02.jar targeting security-.bak, config-.bak, and component-*.bak files (*1)
4 Started Nexus
*1 nexus-db-migrator-3.70.4-02.jar was executed with the following options:
java -jar nexus-db-migrator-3.70.4-02.jar --migration_type=h2 --nexus_work=/var/data/nexus --content
Upgrade from 3.70.4 to 3.79.1:
Step
Action
1 Stopped Nexus
2 Extracted nexus-3.79.1-04-linux-x86_64.tar.gz
3 Executed nexus-db-migrator-3.87.1-01.jar targeting nexus.mv.db (1, *2)
4 Executed VACUUM on the Nexus database (2)
5 Started Nexus
*1 migrator-3.87.1-01.jar was executed with the following options:
/usr/lib/jvm/java-21-openjdk-21.0.9.0.10-1.el8.x86_64/bin/java -Xms4G -Xmx4G -jar ./nexus-db-migrator-3.87.1-01.jar --migration_type=h2_to_postgres --db_url="jdbc:postgresql://localhost:5432/nexus?user=nexus¤tSchema=public"
*2 I have confirmed that the same errors are output when starting with H2, even if steps 3 and 4 are omitted.
Extracts from nexus.log output during Nexus startup.
