Hi @aldvintumbelaka ,
hm, sounds strange. To be honest, we usually do not delete the portaldata prior to transport as it updates the data if its the same portal or creates it, if its a diffrent portal.
Unfortunately the guy doing this in our organization is available from monday on. I will ask him about that process (we started using devops for that, which is itself using the cli tool)
May be a dumb question: you are connected to the right dataverse for the target? And all tables were generated (this may depend on the template used to create the source: when you used sth. service related you may have more table s for the portal as if you only used a custom portal (at least, i think, but not sure 🙂 )
So, will ask my colleague on monday about issues of that type.
Have fun,
Christian
