[indrasenareddy]

Hi All,

We have upgraded our AEM instance from 6.3 to 6.5 and everything went smoothly but the out of box workflow "DAM Update Asset" is not starting at all and throwing the below exception on error.log file. Can you please anyone look into this issue as it final stage of Go Live. 

Exception in error.log

Workflows are stored differently in AEM 6.5. Can you please make sure all the workflows are available in below paths:

/conf/global/settings/workflow/models

/etc/workflow/models

If not, please create a package from 6.3 instance, upload the package to 6.5, restart the instance once and try running the workflow again. Hope this helps.

Hi Diksha, I have tried the mentioned steps but still it is not working.

I would recommend opening a daycare ticket, since you have a tight deadline. They should be able to check the instance, logs and identify the exact issue.
