Installing Dam packages in AEM 6.4

[saicharanm62316]

Hello all,

I am facing an issue when i install the Dam Packages in my new AEM 6.4 instance. I have downloaded the packages from lower environment 6.1. When i install the package there is an error says 

javax.jcr.nodetype.ConstraintViolationException: OakConstraint0021: /content/dam/xxx/xxxx/reform-sbc-external.doc/subassets/0.jpg/jcr:content/renditions/original/jcr:content[[nt:resource]]: Mandatory property jcr:uuid not found in a new node

Can any one help me with this? Appreciate all the help

I'm not sure whether there's a way to get rid of the constraint, but if you add mixin mix:versionable to your jcr:content nodes in your 6.1 environment, the jcr:uuid property will be created and populated automatically for you. That may allow you recreate the package and install.

You can use OOTB JMX MBean to generate jcr:uuid.

com.day.cq.dam (Associate Asset IDs) at http://localhost:4502/system/console/jmx/com.day.cq.dam%3Atype%3DAssociate+Asset+IDs

You can use it for all assets

void migrateAllAssets() Associate Asset ID with all existing Assets

or specify an asset folder to migrate (i.e. to generate jcr:uuid)

void migrateAssetsAtPath(java.lang.String rootPath)
