Criteria to become a RHCA

Hello,

I am currently doing Red Hat certifications , soon will be done with my 5th COE exam . but my RHCSA and RHCE got expired as it was on version 6 (RHEL 6). Also I have two different ID's for RHCSA and RHCE having different and all the other COE exams are on different ID.

could you please tell me if its possible to club these two different ID's and also now what I have to do to get the RHCA .?

do I need to upgrade only RHCE on the current version .? or again have to take both RHCSA and RHCE on the current version .?

Thanks,
