Thank you for raising this. At the moment, the “Check migration readiness” banner in Azure Synapse Analytics is not dismissible and cannot be disabled. This banner is part of Microsoft’s Fabric migration guidance and is currently enabled by design for all Synapse workspaces.
There is no setting in Synapse Studio, no ARM/CLI/PowerShell option, and no policy that can hide or remove the banner. Even workspaces that are not planning to migrate will still see it.
The only supported options today are:
- Ignore the banner (Synapse will continue working normally).
- Submit product feedback, which goes directly to the engineering team: https://feedback.azure.com
I understand this is not ideal, and your feedback is valid. The request for a dismiss/disable option has been shared by many customers, but there is currently no published timeline for when this capability may be added.
Happy to help if you have any additional questions.
