    A container’s partition key cannot be changed in place after creation. Partition key values are immutable, and the partition key definition of a container is fixed once created.

    To use a different partition key, data must be moved to a new container that is created with the desired partition key. This can be done using container copy jobs or, in the Azure portal for the NoSQL API, by using the Change partition key experience, which creates or selects a destination container and copies data from the source container.
