Upgrading to 300c from 300 without web screens

SOLVED

We have a couple of customers on older (v 2012, v 2014) Sage 300 and they are now planning to go to Sage300c v2018.  They don't want to use web screens.

Question - is the upgrade to a "300c" w/out web screens any more complicated than just upgrading to a 300 non-C version?

TIA
