Greetings krishna.vishwakarma. In addition to SKT's recommendation, I would also recommend reviewing the "Brocade FOS Target Path" document which outlines Brocade's recommended FOS versions. You can find it here:
Also, the firmware upgrade procedure is covered here: http://www.brocade.com/downloads/documents/html_pr
And firmware upgrade info on a backbone: http://www.brocade.com/downloads/documents/html_pr
Hope that helps.

Thanks for the links and information. However from the relaease notes I'm not sure if my current version of DCFM will support FOS 6.4 . Is there any information on compatibility matrix for DCFM and Fabric OS .
Thanks in advance

Hi Krishna.vishwakarma. You are correct. Your current installed version of DCFM does not support FOS 6.4. You would need to upgrade to a more current version. I checked the releases notes for v10.4.5a (which was the last release) and that does support v6.4.x. I've attached the release notes for your review.

One more question . We have two switches that needs to be upgraded. So trying to analyze the best approach path to minimize any impact.
Option A ) Do one switch at a time : Say switch A from 6.1-->6.2-->6.3-->6.4 on one day and do the Switch B on a different Day
Option B ) Do both switches on the same day but only one version at a time : Switch A 6.1-->6.2 and Switch B 6.1-->6.2 and later on a different days do 6.2 to 6.3
Thanks in advance

Hello krishna.vishwakarma. I'd recommend option "B". FOS versions tend to play better with each other when the versions are closer together.
