126.96.36.199 is the last version where Classic FDM is released. Therefore your statement is not correct.
From 188.8.131.52, all customers will have to replace FDM by FDMEE.
However in 184.108.40.206.x Classic FDM and FDMEE can coexist in the same installation.
FDMEE is deployed in Weblogic as Hyperion Planning, Foundation Services, etc.
If you want to integrate JDE with HFM then you will have to use FDMEE and license "Oracle Hyperion Financial Data Quality Management Adapter Suite"
Hope that clarifies
