HI Bjørn,

You will need to rebuild these reports as the message clearly indicates you can not import older versions.  This has had to be done for other customers who upgraded their Alliance versions.

Hi Bjorn,

Normally speaking, you would not be trying to import Customizer customizations from 12.5 directly into your live 15.2 environment,

Best practice is to build them in your 15.2 UAT first and then export from there to use as import into production. Didn’t you already have these on UAT?
