Azure Blob Storage Cold Tier was generally available since Aug 10th, 2023. It is a new online access tier that is the most cost-effective Azure Blob offering for storing infrequently accessed data with long-term retention requirements, while providing instant access.
Change feed provides transaction logs of all the changes that occur to the blobs and the blob metadata in the storage account. Now it captures the changes of blobs in cold tier. Object replication asynchronously copies block blobs between a source storage account and a destination account. Now you can asynchronously copy your block blobs in cold tier on the source storage account to a destination account.
Refer to the documentation for additional details.
