Upgrading Brocade Silkworm 3016 from v4.2.1

We have 8 silkworm 3016 integrated with 4 IBM BladeCenter Chassis(2 modules inside each chassis).

We are running v4.2.1 on all them and are in need to upgrade them to atleast v5.3.1 on all inorder to ISL them to CISCO MDS directors as part of a SAN migration project that's underway.

SInce only one or two releases upgrade is supported, we tried to upgrade them to 4.4.1a on couple of switches, but switches will not complete POST after a reboot.

I know it's a really old code, but does anybody have any input to this scenario.

i am not 100% sure, but i heard, certain FabOS Upgrade required first the Blade Center Management Module upgrade.

This is the reason whi your cannot see the Post during Boot time.

I hope this help.

Thanks TechHelp.

We had to go from v4.2.1 to v4.2.1a and then we were able to upgrade to v4.4.1a -> v5.0.5f -> v5.2.3 -> v5.3.1.
