Need to Upgrade DQM to 12.1.4

Hi ,

I need to upgrade to DQM 12.1.4 in order to enable multiple RFC batch servers. I understand that RFC Server Installation is a standalone installation. Do i need to upgrade my Data Services as well in order to use it. Currently I am using 12.2.2.0 .

Also , can somebody share me a document of sorts on how to upgrade it from 12.1.3?
