I assume that all BPS Pro Cron Jobs will run at whatever new Cron Job run times that you have chosen using EasyCron, but you should keep on eye on things for a couple of days to make sure everything is working correctly. BPS Pro cron scheduled events would not happen when they are scheduled to happen in BPS Pro plugin settings. ie AutoRestore|Quarantine would NOT check files every 2, 5, 10, 15, etc minutes and would instead check your website files every X minutes or hours that you have chosen to use instead. Plugin Firewall AutoPilot Mode would check things every X minutes or hours instead of every 5, 10, 15, etc minutes. DB Backup cron shedules would be affected and scheduled backup jobs would not occur at the times you have scheduled them. etc etc etc.
There are a total of 13 BPS Pro Cron Jobs.
