So was your answer politically correct like 'Sir, you should be sure to read the upgrade guide, FAQ, ensure your server and all workstations are compliant with the requirements defined by the publisher, have tested all interfaces, enhancements, third-party solutions, conducted training with existing users, defined how new features will be deployed, backed up the MAS 90 directory, made an image of the server........'
...or, did you say whats really on your mind: 'Oh Hell, go for it! What can it hurt? And by the way, let me give you the name and number of a great guy who does support over the holiday in case you run into any trouble. Unfortunately, I will be out of pocket until February on my annual walk about in the back country of Australia. Good luck!'
