I'm trying to change the type of a column from UUID to TIMEUUID, but I'm unable to do so.

ALTER TABLE Person ALTER KEY TYPE timeuuid;

Error:

Bad Request: Cannot change key from type uuid to type timeuuid: types are incompatible.

Any idea on how to achieve this without losing the data from the column family?
