HANA Certification - Latest Course Materials

Hi All

  I am planning to do HANA certification. As I spoke to the SAP Education the eligibility criteria  to take certification with out training is 1 year experience in HANA and should be working with partner for last 1 year.I heard that recently there is change in the HANA course material before it was TZHANA and TZH300 now they are replaced by HA100 and HA300 , is the content same in both or there is big difference ,by following TZHANA and TZH300 can we clear certification.Request your ideas.

Thanks
