Is it possible to upgrade a Gen4 SAN directly to Gen6 (Without Gen 5 Hardware) ?
For Example : Upgrading a SAN from 300 switches to G610 switches directly
What are the prerequisites, the process and upgrade path to follow ?
none of Brocade Switches ( excepted in DCX Gen4, Core and Port Blade must be replaced ) can be upgrade to newest GenX Series
If you want to upgrade from Gen4 to Gen5 or Gen6, you have to replaced the complete Switches
You are correct. The Gen4 must be at FOS v7.3.1 or later to interoperate successfully with G610 using v8.1.0 or later.
If you connect a simple ISL between Gen4 switches and G610 the zoning database should import onto th G610.
Ensure the G610 domain ID is unique to the existing Gen4 switchs and its defined zone policy setting are the same
as the Gen4's before attaching an ISL.
Ok ! It s clear now.
