At this KB article, I simply describe how to upgrade the firmware version on the Brocade SAN switch. Please check all steps to perform firmware upgrade safely.
Step 1: Check switch configuration
First of all, you need to check your switch configuration to avoid any downtime. If you didn't serve LUNs over two different switches, it means that you need to get downtime to start operation. Because when you start upgrade operation, SAN switch perform reset operation to apply new firmware. So please check your server which you didn't serve LUNs over two SAN switch.
Step 2: Download Firmware
Check this link to download the latest firmware which suitable to SAN Switch that you perform upgrade operation. "Link"
Step 3: Upload Firmware to an SFTP or FTP platform
You need to put firmware on an FTP or SFTP platform which your SAN switch can access.
Step 4: Unzip Firmware Bundle
Step 5: Connect Switch Over SSH to Get CLI
Connect SAN switch over SSH to get CLI. Then run "firmwaredownload" command to start operation.

Step 6: After HA Reboot Check Firmware Commit Status
