Yes - for upgrading this is what we do. The thing is the first server was a pilot for my team and now we have a proper server for the company (but it was a pilot too so we didn't migrated all the old experiments). To make sure I understand the paid service - do you want to have a short phone call to explain the different options - is it a complete support or can we pay for specific support tasks? It worth mentioning that I'm not the decision maker in the company but I would like to have some information to present
