Hi,
I am trying to migrate experience builder from one Portal organization to another. Workflow: Solved: Re: Replicate Experiences between portals - Esri Community
I have downloaded the experience from source portal. Made the changes (Changed Portal URL) to config.json file.
When uploading the zipped folder into target portal ExB, I am getting error "Error: This is an experience. Please switch to experiences tab and try again".
The version of both source & target exB is 1.15.
