Good morning all,
First of all thanks in advanced for your help.
I have a new Brocade 300 switch for a Metrocluster enviroment. This new switch has a FOS version 7.2.1 and the other 3 old switches has the 6.1.1a.
I'm not able to find if i can do a downgrade directly from 7.2.1 version to the 6.1.1a version.
Could someone help me?
No (at least, it is not supported). Supported upgrade/downgrade paths are single major version non-disruptive or two major versions disruptive. This would be 7.2 -> 7.1 -> 7.0 -> 6.4 etc.
Is it hardware replacement of failed switch?
Thanks for your answer Aborzenkov,
Yes is a hw replacement.
