I have been RHCE in RH OpenStack for almost 3 years. I took both exams EX210 and EX310 on OSP 6. I now need to consider renewing those certifications.
When I took EX310 at the time, it automatically extended my EX210 for 3 more years.
Is the current EX310 exam based on OSP10 still able to extend my old EX210, even though I took it on OSP 6 ?
I figured out that for EX200/EX300 exams, the latter extends the former until the public availability of RHEL major version n+2.
Does the same principle applies to EX210/EX310, with OSP long life releases (6, 10, 13) instead of RHEL major versions ? Just speculating here. I hope not.
I think that yes, If you take the EX310 and pass it, and at that time your EX210 is still valid, the EX310 would extend your EX210 validity.
But, for being 100% sure about this, I recommend you to make this question here:
