I finally updated my VB3-II on my MBP this afternoon after finishing yesterdays last gig with the VB3-II 1.1.1 
THIS IS NOT AN ORDINARY UPDATE
As the VB3-II 2023 was annonunced as a “totally rebuild” I was expecting some issues, and I was not disappointed:
About the installation (or update) itself we already had some discussion earlier in this thread.
For me it was about to renew my last existing rackspace providing 7 variations for my main gig file
Learning #1:
the parameter mapping is completely different (at last compared to my previous installation). All my widget assignments have been mixed up. (16’ Drawbar on Delay Time, 5 1/3’ on Reverb etc.). Therefore none of my variations was working anymore 
Learning #2:
the Leslie Half Moon Switch is now acting like in other B3 Instruments (CC#1 Slow-Brake-Fast). Mapping needs to be adjusted…
Learning #3:
the behaviour of the Volume Pedal can now be fine tuned inside the VB3-II. Something I have to look deeper later on
So after playing around with the mapping my old rackspace I began the transfer. This is the scheme which worked out with low effort
- reload the gig file, select the VB3-II rackspace to change and create a new variation. This is needed to avoid changes in the existing variation when assigning the ‘new’ parameter
- select this variation and (re-)do the complete mapping (including new mapping for Halfmoon Switch…)
- open the VB3-II and select a preset (the preset I remembered when I build up this rackspace…) to get a working organ
- turn of SPLIT (which seems to have been activated somewhere in this process)
- save…
Currently I have an updated rackspace which feels close to the previous one.
But I think I will need some tweaking within the next week - I’m looking relaxed forward towards my next gig end of December
