Hi @akank_23,

Can you confirm if oak-run version used is same as that of your instance. Please share your AEM and Oak version(as available in the instance)


If you are following the steps mentioned in the this article - https://experienceleague.adobe.com/docs/experience-cloud-kcs/kbarticles/KA-16542.html

and if you have backup of your instance's segmentstore,

  • I suggest to restore the same and follow steps 1 - 5 alone. 
  • If you have repo.lock file, delete that as well after step 5 -> try to restart the instance at this stage and see if it works. 

If you still face issues, please share the sequential steps followed and stack error trace.

Ok. Did you get a chance to try the procedure again as said previously (By restoring the backup -> trying again till step 5)
