Brocade DS-300B

No. You can't do it non-disruptively. You need to go 6.4 -> 7.0 -> 7.1 -> 7.2 -> 7.3 -> 7.4 (I think). A disruptive upgrade can go 2 versions at once, but I've never done it.

The problem is getting hold of all those versions. Broadcom has severly restricted what you can download and Dell doesn't have the old versions available for download any more, because Broadcom said so.

@SteveK821​ Thank you 

There is anyway to download these versions (7.0, 7.1, 7.2, 7.3)?

Thank you again

@Mar3i​ I don't know if it's available anywhere else. I have them locally, but I'm not allowed to distribute them. Maybe ask Dell Support if they might be able to provide it on a temporary basis.

@Mar3i​ Hi, you need a valid support contract. Then open a support SR, and they will need to contact Brocade and only will be able to get the firmware when the support contract is also approved by Brocade.

thanks,

Ed

@SteveK821​ Anyway to get them as Dell Support told me that they not available now for download.

Appreciate your help 

Thanks
