Hello Rajesh,

Go to /oak:index/damAssetLucene/indexRules/dam:Asset/properties/dcTitle and check the type of property "name".

It should be String instead of Strings array, Strings[].

Hi Vish.dhaliwal​

Thanks for your response, its already with String.

Hello Rajesh,

There might be some issues in migration itself.

- Is this the first time you started the instance after migration?

- What is the migration command you used?

- You said it is a fresh install, so I believe it is the sidegrade not in-place upgrade. Is that correct?

Vishu

Yes, the first time after migration. Its a sidegrade.

OAK-Upgrade 1.8.3.command was used to migrate as we use 6.4.1 which is with OAK 1.8.3

I dont see any issues with migration, however there is some configuration tweek needed in OAK index which is hitting this WARN.

Anything you suspect ?

Thank you,
