 ## Migrate data directly to the most cost-efficient access tiers
 
 Choosing the most optimal tier up front can reduce costs. If you change the tier of a block blob that you've already uploaded, then you'll pay the cost of writing to the initial tier when you first upload the blob, and then pay the cost of writing to the desired tier. If you change tiers by using a lifecycle management policy, then that policy will require a day to take effect and a day to complete execution. You'll also incur the capacity cost of storing data in the initial tier prior to the tier change.

 ## Set the default access tier for a storage account
 
 The default access tier setting for a general-purpose v2 storage account determines in which online tier a new blob is created by default. You can set the default access tier for a general-purpose v2 storage account at the time that you create the account or by updating an existing account's configuration.

 Archive storage is the lowest cost tier. However, it can take up to 15 hours to rehydrate 10 GiB files. To learn more, see [Blob rehydration from the Archive tier](archive-rehydrate-overview.md). The archive tier might not be the best fit if your workloads must read data quickly. The cool tier offers a near real-time read latency with a lower price than that the hot tier. Understanding your access requirements will help you to choose between the cool, cold, and archive tiers.
 
 The following table compares the cost of archive storage with the cost of cool and cold storage by using the [Sample prices](#sample-prices) that appear in this article. This scenario assumes a monthly ingest of 200,000 files totaling 10,240 GB in size to archive. It also assumes 1 read each month about 10% of stored capacity (1024 GB), and 10% of total transactions (20,000).

 Consider a scenario where data is frequently accessed during the early stages of the lifecycle, but only occasionally after two weeks. Beyond the first month, the data set is rarely accessed. In this scenario, hot storage is best during the early stages. Cool storage is most appropriate for occasional access. Archive storage is the best tier option after the data ages over a month. By moving data to the appropriate storage tier based on its age with lifecycle management policy rules, you can design the least expensive solution for your needs.
 
 Lifecycle management policies are supported for block blobs and append blobs in general-purpose v2, premium block blob, and Blob Storage accounts. Lifecycle management doesn't affect system containers such as the `$logs` or `$web` containers.
