Demantra (12.2.4) a Compatible version for EBS 12.1.2 and VCP 12.1.3.7?

Our Client is on EBS 12.1.2 version and VCP 12.1.3.7 ( Centralized Instance) and a separate instance for Demantra (Current version is 7.3.1.3.)

Demantra: 7.3.1.3

VCP: 12.1.3.7

EBS: 12.1.2

1) What the most compatible & certified version of Demantra to be considered for upgrade, without impacting VCP 12.1.3.7 and EBS 12.1.2? is Demantra 12.2.4 is compatible with EBS 12.1.2 and VCP 12.1.3.7?

2) Also, does VCP needs any upgrade as well?? if so, what are the pre-requisites and compatible version of Demanta and VCP with EBS 12.1.2

Thanks for your help in advance.
