Looking at pricing now I'm just wondering what is different if I compare old LTD plans with what you are offering now. I have Tier 4 old plan so even If I upgrade what do I get more for Tier 5 or 6? Only "Cloud execution hours" which can be purchased directly with you for one-time fee depending on how many hours I need am I right? I'm not talking about more robots, users etc. I want to see what I'm missing with my Tier 4 compared to to Tier 5 or ^ in terms of features.
