The server 2017 install is much much smaller than prior versions. I assume this is because the deployment components (toolkit) are no longer part of the install?
It appears that you can only deploy to a 2017 server from PB2017? This is because the toolkit is only available as a PB 2017 update? So if you are not currently running PB 2017, then you are not able to use server 2017?
There also appear to be licensing changes in server 2017? It is now only CPU based restrictions?
