I just installed Robohelp 2015 upgrade from Robohelp 10, and am getting ready to work on my 30 child projects. Do I need to recompile the parent before publishing? Do I need to compile ALL the child projects before publishing?

First make sure you’ve loaded all the available patches; then makes sure you’ve got a backup of your RH10 work; then open each of the projects and let RH2015 upgrade them; save them all then reopen and start your usual generate sequence (children first, then the parent, right?)
