Updating 5 => 6 Documents Panels Data gone

Updating pimCore Version 5 => 6 Documents Panels Data gone
I don’t have any types of error also my all functionality working fine on front end.
Also i have tried clear cache and reinstall assets.

Any ideas what could help?

have you tried opening dev tools while loading pimcore and see what errors appear?

have you also run the pimcore migrations after upgrading?

Thanks for your help :slight_smile: .

Now it is working perfect.

I have added “symfony/symfony”: “^3.4.17” on composer.json file then update composer and run pimcore migrations.

Thanks.
