Are the Mango 3.0 Upgrade Notes written April 26, 2017 accurate for upgrading from Mango 2.8.8 to Mango 3.3? Are there any upgrade issues that will break features in 2.8.8? I'm especially concerned about not breaking the old Graphical Views, meta scripts, and global scripts, Modbus, and BACnet. If I backup the SQL database, /opt/mango, and TSDB, is it then safe to upgrade via the Mango Module page? What will break?
