Abstract
Techniques are described for migrating data from a first table to a second table while transforming at least one characteristic of the data. Characteristics transformed may include one or more of an encryption key or method, a table schema, a data structure, or a storage infrastructure. Migration may be performed in two or more phases. A first phase may migrate and transform a majority of the data, such as data that is older than a certain threshold age. A second phase may migrate and transform the remaining, newer data. A status table may indicate which tables are active and are to be written to and read from during data writing and data consuming processes. Moreover, embodiments support data replication across multiple regions.
