Azure AI Search has two new self-serve options that make it easy to change or upgrade your service, directly from Azure portal or the management API.
Changing your service tier is now as easy as adding partitions or replicas; no rebuild required.
Self-service option to perform upgrades to new service capabilities, like increased capacity limits or improved features, without having to recreate the service or reindex data.
Change service tiers between Basic, S1, S2, and S3 tiers. Free, S3 HD, L1, and L2 services are not eligible to change their tier.
Service upgrade increases total storage in your service to the higher capacity limits available for new services.
At time of release, service upgrade will be available in select regions, with more regions added in the coming months.
