Ets5 Home or Ets

Hi

I don’t have ETS, but I own a house where KNX is installed. I’ve used two different installers for the main installation and upgrade some years later. The structure in the ETS are different between those two projects. I want to adjust  this. The installation has now 51 devices in total and run on ETS4. I have IPgw, to the knx, from Bab Starter.

I want to do changes by my self, and are planning to purchase either ETS5 or ETS5 Home. 
since I have less than 64 devices I can use Home edition. 
I operate the Bab starter applications my self, but I can’t change anything in the Ets. 

How can I migrate from ETS4 to ETS5 Home? Can I follow standard procedure?

Regards
