Issue:
Required firmware version before successfully upgrading to 5.4.x and later version and where to download it

Product Line:
NetBotz

Environment:
NBRK0750
NBWL0755

Cause:
When upgrading to newer firmware versions, customers might encounter an error. Upgrading directly from versions prior to v5.3.5 to versions starting from v5.4.x can cause the upgrade to fail.

Resolution:
When upgrading to any version newer than v5.3.5, the appliance needs to be at least on v5.3.5 to upgrade to target version successfully. Attached is the v5.3.5 firmware to enable upgrading an appliance that is currently on 5.3.4 or earlier to latest version.
