I need to upgrade a Zone Director 1100 from firmware: 184.108.40.206 build 14 to 220.127.116.11.63 (MR2 Refresh4). I cannot find a suitable upgrade path of versions that is officially supported.
Can anyone offer some assistance.
This information is detailed in the release notes for each version.
Release notes for 9.10.2 can be found here: https://support.ruckuswireless.com/documents/2401-zonedirector-9-10-2-mr2-refresh4-release-notes
The earliest version you can upgrade from is 18.104.22.168.205 (9.9 GA release). So you will need to download the firmware file and release notes for 9.9.0 to check you can upgrade directly to that version from you current 9.8.3 version.
I hope that helps,
The upgrade path information is in the release notes document for 9.9.1:
As you are running a later version of the 9.8.x code (MR3), then you can upgrade directly to 9.9.1. I suspect the release notes for 9.9.1. were written prior to the release of 9.8.3.
Officially Supported 9.9.1 Upgrade Paths
The following ZoneDirector builds can be directly upgraded to ZoneDirector build 22.214.171.124.31:
126.96.36.199.9 (9.7 MR 2)
188.8.131.52.373 (9.8 GA)
184.108.40.206.99/101 (9.8 MR 1)
220.127.116.11.15 (9.8 MR 2)
18.104.22.168.205 (9.9 GA)
22.214.171.124.212 (9.9 GA refresh 1)
126.96.36.199.216 (9.9 GA refresh 2)
If you are running an earlier version, you must first upgrade to one of the above builds before upgrading to this release.
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.
Always ensure you take a config backup prior to performing an upgrade.
