Volvo V/S90 front seats retrofit/standalone. - Working solution!

[Kamil]

Hi everyone,
I’m planning a seat upgrade on my 2017 Volvo XC90 and could use some advice from anyone who has done a similar retrofit.
Current Setup:

• 2017 XC90 with fully electric, heated front seats (with memory).
  

Donor Setup:

• Fully electric front seats from a 2022 XC90 with both heating and ventilation (which is the main reason for the upgrade).
  

My Questions:

1. Is this a straightforward plug-and-play mechanical and electrical swap, or are there wiring/pinout differences between the 2017 and 2022 MYs?
   
2. Will I need to replace or add any modules (e.g. under-seat modules), or will the donor seats' existing modules work once configured?
   
3. Regarding software: I have Orbit and noticed the option to enable heated + ventilated seats in the config. Is Orbit software activation enough to get the ventilation working properly, or is additional Volvo OEM software required?
   

Any insights, tips would be greatly appreciated!
Thanks in advance!
