Best Practice for Changing Benefit Group on Employee While Retaining Same Benefit Plans

I'm looking for guidance on the recommended approach for changing the Benefit Group assigned to a group of employees in JDE E1 HCM.

Current Situation:

• Employees are currently assigned to Benefit Group A.
• We need to move them to Benefit Group B.
• The actual Benefit Plan IDs will remain the same.
• We have already configured the new Benefit Group and associated Categories, and we've added the same Benefit Plan IDs that existed under the old Benefit Group.
• Which means that they have the same EE DBA's and elections.

What is the recommended best practice for updating the Benefit Group on the Employee Master and updating EE level DBA's (if required)?
