Dell Sonicwall updates

[CAWJames]

Afternoon all,

 

We currently run an NSA 3600 Dell SonicWall router. We are currently at software level "SonicOS Enhanced 6.2.2.2-19n" which is a firmware from Jun 18, 2015.

 

I want to upgrade, but anything newer is either a step back to 6.1 or in Beta.

 

Does anyone else use these, and do you jump to beta? Or do you stay until the beta becomes mainstream(which is not very fast...)

 

Thanks

 

James
