I have a ZD1100 with 5 zf 7372 and 1 R700 on the network. As of this query, running 22.214.171.124.15 firmware. I first read the release notes for 9.10.2, which advises that it's best to upgrade from a 9.9.0, 9.91, 9.10.0 or 9.10.1 release.
OK, so I go read those notes to confirm I'm on a supported path, and in this PDF: https://ruckus-support.s3.amazonaws.com/private/documents/745/ZoneDirector%209.9.1%20Release%20Notes...
In that PDF, I find this eyebrow-raising statement:
NOTE: The upgrade path from 9.9.1 to 9.10 is not recommended due to the fact
that the 9.10 release date occurred before 9.9.1 and therefore 9.9.1 includes bug
fixes that are not in the 9.10 code.
If I wish to bring a ZD1100 to the most current supported firmware, can someone confirm the desired release number? Incrementing digits say it should be 9.10.X, but the above says that's not the case.
