Role Mapping Mass Update GRC AC 10

Hi Experts.

I need to update the role mapping from aprox 50K composite roles.

In mass update seccion at NWBC, I couldn't find the option "role mapping" or similar to make this task.

Is there a way to mass update role mapping? any recommendation?

My scenario:

ECC Role A --> mapped to EP Group_A (old EPSystem)

update to:

ECC Role A --> mapped to EP Group_A (new EPSystem)

Thanks in advance !!

Regards.
