============================== Update a Primary Key

Topic: Can you Update a Primary Key in ScyllaDB?

Audience: ScyllaDB administrators

In ScyllaDB, you cannot update a primary key. It is impossible to do so.

However, you can migrate the data from the old table with the old primary key to a new table with a new primary key. There are two ways to handle the migration:

• Fork-lifting the historical data with the :doc:Spark Migrator </using-scylla/mig-tool-review/> tool.
• Double writing the new data.
