How things work- redundancy of gateway without global project

Hi All
I try to verify and understand something that i was told regarding gateway redundancy.
I was told that if the gateway has for example 5 projects but there is no master global project which contains the settings which are inherited by other project then redundancy will not work . Can anybody please comment if this is true and why would it not work so i can understand it deeper?

Regards

That is absolutely not true.

Redundancy works between two gateways. They will automatically synchronize state from ā€˜masterā€™ to ā€˜backupā€™, including all tags, projects, device connections, etc. Thereā€™s no ā€œmaster global projectā€ - there was a ā€œglobalā€ project in 7.9 that was special from the perspective of the project system, but it had no bearing on redundancy at all.
