We have been testing the solution with mac OS 10.11.6 fms 15.01.21 developer license 3 user cap and the client needs 5 users by midnight tonight.
I have another mac OS 10.11.6 running fms 15 trial 15.02.206 with 13 days left. As I write this question I think I should just move the files to the
15.02.206 and go about changing all the launchers and remote client logins.... then upgrade the license. Thanks for your help.
