Mixed switch SAN firmware upgrade

[Anonymous]

I have two fabrics build around 2 - 3800 switches running v3.2.0 firmware and 1 - 4020 blade center switch running 5.0.4a firmware. I am planning on upgrading the firmware on both types of switches:

Any known interoperability issues with this combination of OS's? (I haven't found any)<BR><BR>-&gt;&gt;&gt; Latest Compatibility Matrix can be Download here:-&gt;&gt;&gt; Upgrade First both 4020 Blade switch v5.0.5a ( by the way the latest is v5.0.5c ) after upgarde is completed upgrade teh both 3800. <BR><BR><BR>4.
