Koen Verbeeck lays out a warning:
I’m in the progress of migrating some legacy stuff at a client, and in their Power BI environment there are still quite some Power BI dataflows Gen1. I had migrated an Azure Synapse Dedicated SQL Pool to an Azure SQL DB (much cheaper for their volume of data), and in the dev/test environment all dataflows were switched correctly to the new database.
However, in production, the dataflows only wanted to connect to the Azure SQL DB production database through a gateway. Weird, right?
