Configure continuous aggregate migration
The migration procedure provides two boolean configuration parameters, override and drop_old. By default, the name of your new continuous aggregate is the name of your old continuous aggregate, with the suffix _new.
Set override to true to rename your new continuous aggregate with the original name. The old continuous aggregate is renamed with the suffix _old.
To both rename and drop the old continuous aggregate entirely, set both parameters to true. Note that drop_old must be used together with override.
