I try to upgrade our Nexus from 3.0.2 to 3.1.0 (or later).
I’ve done all the preparations described here (How to Upgrade Nexus Repository Manager 3.0.2 to 3.1.0 or Later – Sonatype Support).
The Update always fails with the failure:
“File ‘key_store_name_idx.sbt’ already exists”.
If i rename the file …/sonatype-work/nexus3/db/.
If I start the nexus again the following error occurs:
“[FelixStartLevel] *SYSTEM org.sonatype.nexus.upgrade.internal.UpgradeServiceImpl - Problem upgrading config from 1.0 to 1.1
com.orientechnologies.orient.core.exception.OSchemaException: Cluster with id 23 already belongs to class upgrade_model_versions”
Can anyone help me upgrading the application?
Thanks and Regards.
