Hello @Kenny ,
Thank for the ask and using the forum .
- I think you can use the DWU used metrics to get more info on the usages . Please do read about this here
- I need to understand as to what do you mean by migration here . Serverless synapse somes with the analytics workspace is used to query data in the lake , I am sure that the dedicated SQL is far rich then serverless , You can read about this more here .
Thanks
Himanshu
