Expiration date of C_TADM55a_75 certification

Hello community!

Recently I have been sadly surprised because I have seen on the website that the certification “C_TADM55a_75 - SAP Certified Technology Associate - System Administration (SAP HANA) with SAP NetWeaver 7.5” expires on December 31, 2021. Besides, I have seen that a new certification “C_TADM_21 SAP Certified Technology Associate - SAP S / 4HANA System Administration” exists which is practically the same as the one mentioned above.

During 2020 and in this year, even after getting the certification, I accessed the certification website C_TADM55a_75 several times and I never saw that validity date. Now overnight I see that the certification which was so hard to achieve has been replaced by one that is almost the same.

I also note that the same certification, but with the database ASE C_TADM54_75 - SAP Certified Technology Associate - System Administration (SAP ASE) with SAP NetWeaver 7.5 has no expiration date.

I would like to know if the end of validity date of the certification C_TADM55a_75 is a mistake due to the similar contents. In case the expiration date of December 31, 2021 was correct, I would like to know how my company might be affected when it comes to managing SAP Netweaver 7.5 systems.

And finally, I would like to know what it means that the certification expires on December 31, 2021.

Could you help me clarify these doubts?.

Thank you in advance.

Kind regards.
