Hello Dmitry Anyushin,

you can't use CPUs with different firmware as H-System. For a H-System you have to use the identical CPUs (thats include the firmware). See the manual SIMATIC Fault-tolerant systems S7-400H at section 3.2 Rules for the assembly of fault-tolerant stations.

So you have to update the firmware of the old controller.
Under follow link you can find the updates for the firmware Operating system update: CPU410-5H Process Automation 

With regards
Heisenberg
