Most current firmware for zd1100 installation? (October 2016)

[steve_yuroff]

Hi all,

I have a ZD1100 with 5 zf 7372 and 1 R700 on the network.  As of this query, running 9.8.2.0.15 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.

That note is about the 9.10 GA (9.10.0.0.218).  9.10.2 is definitely newer than 9.9.1, and has more bug fixes.

You'll see this fairly often with some manufacturers- a maintenance release to an "older" release is actually newer than the latest "new" release, at least until the "new" release gets a patch.  9.10.1 was that release in comparison to 9.9.1.

I have updated from 9.9.1 to 9.10.1+, and had no issues with doing so.  That being said, my typical upgrade path from what you are running is 9.8.2 -> 9.9.0 -> 9.10.2.  I would suggest doing it as soon as feasibly possible due to the NTP bug present in your release.

I appreciate the info, Mitchell.  Let me throw one more detail at you: there are 3 releases of 9.9.0: 
9.9.0.205 = GA Software Release
9.9.0.212 = GA Refresh
9.9.0.216 = GA Refresh #2.

For your middle step of your workflow, would you consider the version of the 9.9.0.x family chosen to be arbitrary, or is there a reason to use or avoid any particular option?

[mitchell_axtell]

The refresh version does not matter- any upgrade path the GA release supports is also applicable to the refreshes.

In case anyone revisits this slightly convoluted thread latest 9.10 (as of Nov 2016) is now 

9.10.2 build 29 (aka 9.10.2.0.29 aka 9.10.2 MR2)

in release notes there are numerous security fixes from interim builds 16 & 22...been on my ZD for 2 days and is running fine.

Ha!  Thanks for pointing this out.  I brought my ZD up to 9.10.0.2.11 just a few days back, and I thought I was current.  You show me I'm not.

What's the ideal way to stay informed of new ZD firmware releases?  Does Ruckus tweet them, have an RSS feed...?
