crx2oak producing CommitFailedException: OakConstraint0030: Uniqueness constraint violated at path ...

Hi,

We're using crx2oak to do blue-green deployments. As a baseline I'm trying the parameter --copy-versions=false to see how much time/space can by gained by excluding versions. However when doing this, in the migrated repository on startup, I consistently get this error:

It surprises me that NOT copying versions causes this. On the other hand, I've seen that copying some versions fixes this problem. I'll continue trying options, but any tips or guidance about what's happening would be very useful.

Thx,

Federico

PS: aem 6.1 SP2

PS2: curiously enough the mentioned uuid belongs to the anonymous user at /home/users/G/GDBwO...

Hi,

What is the exact command you are using to migrate?

Thanks,

Hi,

java  -jar ${UPGRADE_JAR} --mmap --copy-versions=false --copy-orphaned-versions=false --include-paths=/content,/etc/tags,/home,/var/<removed>/widgets,/jcr:system/rep:namespaces,/jcr:system/rep:permissionStore,/etc/workflow/instances,/var/eventing/scheduled-jobs,/var/eventing/distribution --merge-paths=/var/audit ${SRC} ${DEST}

That's an interesting case. Can you post it to an Apache Oak mailing list? Please include your Oak version as well.

Yeah, that's a good idea. For other people's reference it's ticket 1435759.

Update: simply excluding the anonymous user seems to have fixed the problem. It's a dynamic path though.
