Abstract
One example provides a method of migrating a data partition from a first storage cluster to a second storage cluster, the method including determining that the data partition meets a migration criteria for migrating from the first storage cluster to the second storage cluster, on the first storage cluster, preparing partition metadata to be transferred, the partition metadata describing one or more streams within the data partition and one or more extents within each stream, transferring the partition metadata from the first storage cluster to the second storage cluster, directing new transactions associated with the data partition to the second storage cluster, including while the one or more extents reside at the first storage cluster, on the first storage cluster, changing an access attribute of the one or more extents within the data partition to read-only, and on the second storage cluster, performing new ingress for the data partition.
