Hi, tried the new free v15.5 looks great, very clean and easy to use. Quick question (no.1), I'm currently on V14 Pro and want to setup V15.5 Pro (with my license key) and get everything ready to switch over and do a few more tests etc. Can I run both my v14 and v15.5 off the same license for a few days whilst I get everything moved over, or will activating the license on V15.5 disable my v14 install (thinking 7 days max). Also (question 2), I believe there has been some change of position re the use of a license on a second backup machine. My idea, once all setup and working was to clone the machine and use FTP to backup config and restore to second machine once a day. If first machine ever failed I would manually alter external DNS to point to the backup server. Can I confirm this now requires two licenses even through it's not an automated failover and the external FQDN will remain the same for both servers. Guess it's not the end of the world If I can't do this as the footprint of the Unix install is so low a snapshot could be restored pretty quickly. Regards, David.
