Good day team,
There is this potential customer that has 4 brocade switch 510 with firmware 6.3.1a...they are planning to upgrade the firmware. please what is the maximum firmware that can be achieved on the switch and the upgrade pahts?
i think you mean Brocade 5100 switch and not 510.
If so, the latest supported firmware is 7.4.1e.
For nondisruptive upgrade you have to go from 6.3->6.4->7.0->7.1->7.2->7.3->7.4 so 6 updates at all
