Azure Database for MySQL: Regional access restriction — Operation fails with ProvisionNotSupportedForRegion error

Problem description

I am attempting to perform a major version upgrade of my Azure Database for MySQL flexible server from MySQL 8.0 to 8.4 using Azure CLI. The upgrade fails during the temporary provisioning step in France Central with the error code ProvisionNotSupportedForRegion, indicating that provisioning in the requested region is not supported. The operation requires the General Purpose SKU in France Central, but it appears my subscription does not have access to this region or SKU.

Environment

Service: Azure Database for MySQL flexible server; Region affected: France Central; Method used: Azure CLI; Source version: MySQL 8.0; Target version: MySQL 8.4; Initial SKU: Burstable B1ms; Temporary SKU: General Purpose Standard_D2ds_v4 (2 vCores) in France Central.

What I've already tried

I have reviewed the support case details and confirmed that the error occurs before the upgrade process begins, due to regional provisioning restrictions. I have not attempted to manually change the server SKU or rerun the upgrade without verifying regional access. No additional CLI logs or diagnostics beyond the initial error are available.

Current status

I am seeking assistance to verify and enable regional access for the General Purpose SKU in France Central for my subscription. Once access is confirmed, I plan to rerun the upgrade to MySQL 8.4. I need guidance on how to proceed with regional access requests and confirmation that the SKU will be available for my subscription in the specified region.
