This should first be tested on a development system before being deployed to a live system. My steps may be incomplete, some binary upgrades will require new system keys or may require a utility to be run beforehand. Always test first!
Ensure no-one is using the Binary being upgraded, it is recommended for all users to log off Sage whilst updating binaries.

Check the binary version by going to Help –> About –> Versions Tab
