that I am aware of, the upgrade notifier has not yet been enabled.
This is likely due to (a) serious bug(s) that have been found by either QA when testing the upgrade feature or normal users whom have chosen to upgrade their MGA-6 via other means.
If you are still on MGA-6 and wish to upgrade, be aware that since the upgrade notifier has not been enabled, there is a high likelihood of failure.
If you feel you are capable of performing the upgrade and and are able to resolve any issues, and MGA-7 has features that you need, you are welcome to perform the upgrade by other means.
best of luck
