SRM license per-VM and dependecies with virtual machines OS, DB and installed applications

Hi all,

I have a vmware cluster Enterprise Plus ESXis licensed and a cluster Enterprise ESXis licensed.

my goal is to have a solution to replicate VMs in the my primary datacenter to the secondary site (one way).

I want to have vCenter SRM license for 30 VMs selected dynamically from time to time.

My question is :

Is there any SRM dependencies with OS, DB software, Applications installed in my VMs.

in other way : can I use SRM license to replicate any type of OS, DB,... or SRM activation will change depending on what specific VM i want to manage??

Thank you very much for your responses.
