@JorneS Thanks for reaching out. To clarify, the stv1 and stv2 compute platforms are different versions of the Azure API Management service. The stv1 platform is an older version of the service, while the stv2 platform is the latest version of the service. The stv2 platform includes several improvements and new features please refer: https://learn.microsoft.com/en-us/azure/api-management/compute-infrastructure#what-are-the-benefits-of-the-stv2-platform
where as the v2 pricing tiers (https://learn.microsoft.com/en-us/azure/api-management/v2-service-tiers-overview) are a new set of tiers for API Management. Hosted on a new, highly scalable and available Azure infrastructure that's different from the stv1
and stv2
compute platforms, the v2 tiers aren't affected by the retirement of the stv1
platform. please refer: https://learn.microsoft.com/en-us/azure/api-management/compute-infrastructure#what-about-the-v2-pricing-tiers
https://azure.microsoft.com/en-us/pricing/details/api-management/
so, to answer your question you will be still in developer sku after migrating to stv2.
I hope this helps! do let me know incase of further queries, i would be happy to assist you.
