To move from Basic to a Standard tier and resolve the “quota exceeded” error, two things are needed:
- Ensure the target tier (Standard) is allowed and has capacity in the subscription/region.
- Request a quota increase for Azure AI Search in that subscription/region if needed.
Follow these steps in the Azure portal for West US:
- Check current Azure AI Search quotas
- In the Azure portal, go to Quotas from the global search.
- On the Overview tab, select the Search tile.
- Filter by Subscription and Region = West US, and (optionally) by Usage to see what is close to the limit.
- Locate the quota entries for Azure AI Search in West US (for example, number of services per tier/region).
- Request a quota increase for Azure AI Search
- In the same Quotas blade, next to the relevant tier/region entry (Standard in West US), select Request adjustment (pencil icon).
- In New Quota Request, set a New limit that is higher than the current limit (for example, increase the count of Standard-tier search services allowed in West US).
- Submit the request.
- Monitor Azure portal notifications; most requests are processed within 24 hours. If capacity is constrained in West US, the automatic request may fail and a support incident will be opened for manual review.
- Retry upgrading the search service
- After the quota increase is approved, go to the existing search service in West US.
- Select Settings > Scale.
- Choose Change Pricing Tier and select the desired Standard tier (S1, S2, or S3), ensuring the configuration stays within the service limits.
- Save the change and wait for the operation to complete.
If the quota request is rejected due to regional capacity constraints, consider:
- Keeping the service on Basic and scaling via more partitions/replicas (if within limits), or
- Creating a new Standard-tier search service in a different region that has available capacity and migrating indexes and data.
