Upgrade Path VOSS 6.1.2.1 to 8.5.1.0

[PerryD]

I have over 100 VSP Switches to upgrade and am looking to confirm how I get from 6.1.2.1 to 8.5.1.0

Are there any steps or do I go straight to it?

Thanks!

Hello Perry, 

To upgrade VOSS from 6.1.2.1 to 8.5.1.0, based on Release Note information, supported upgrade path is : 
6.1.2.1 -> 8.1.x -> 8.5.1.0
I recommand to use the 8.1.10.0 release. 
but WARNING ! Current (6.1) management system is rebuild in 8.2+ to move on a segmented management. If you upgrade without any change, you will loose your managment access. 
I recommand to you to read the Release Note of 8.2.0 software to check which modifications you need to do.
