Replacing a Shower valve

[Uncle_Nige]

Hello,
I currently have installed and working an Axor Starck X manual shower mixer:

Axor Starck X*Single Lever Shower Mixer for concealed installation | Hansgrohe International

I want to upgrade it to the thermostatic version:

Axor Starck X*Thermostatic Mixer for concealed installation | Hansgrohe International

Is it simply a matter of taking out the manual one and replacing it with the thermostatic version, or do I need to do anything else with the pipes etc...

Thanks very much in advance.

yes, but do read the manufacturer instructions first.

Thanks!
Presumably the replacement would need a separate shut off valve?
