We had older version of nexus and a new docker image of nexus was pulled and now all configs are gone

We were running a very old version of nexus3 3.10. we were using to store all our docker images and then via Jenkins we pulled them down.

our dockerfile for the task was setup to pull sonatype/nexus3. the container died due to an OOM error and the new nexus3 image was pulled down and build. of course its 3.25.

Now all our repos are empty. no images, nothing. no users, etc. looks like a default install.

Could getting a new version like that have caused an issue? i checked the location of orient db and the version of orientdb appear to be 3.25
/nexus/system/org/sonatype/nexus/nexus-orient
./nexus/system/org/sonatype/nexus/nexus-orient/3.25.0-03
./nexus/system/org/sonatype/nexus/nexus-orient/3.25.0-03/nexus-orient-3.25.0-03.jar
./nexus/system/org/sonatype/nexus/nexus-orient/3.25.0-03/nexus-orient-3.25.0-03-features.xml

any possibility of getting our stuff back?

I would hazard you didn’t maintain the storage between the two containers.
