I try to upgrade to 22.214.171.124.32 from 126.96.36.199.17, the ZD1100 controller can upgrade to 188.8.131.52.32, but the Zone Flex 7982 was failure to upgrade to 184.108.40.206.32. Then, I prepare to following the upgrade path. When I find out the 9.7 release version I cannot find the 220.127.116.11.16 from official supported website https://support.ruckuswireless.com/products/29-zonedirector-1100#firmwares
So, If I try to upgrade to 18.104.22.168.32 again, I need to download 22.214.171.124.16 version? Or I just upgrade to 126.96.36.199.9, it can upgrade to 188.8.131.52.32?
you don't need to upgrade the ZF, the ZoneFlex will get updated from the ZoneDirector. you don't have to install a version in between, all listed versions can be upgraded in one step. you can also upgrade to 184.108.40.206.53 then you have the "KRACK" patch. but you only get it before 31.jan.2018
I have try to upgrade to 220.127.116.11.53 / 18.104.22.168.32, but when I successful to upgrade to 22.214.171.124.32, ZF7982 cannot upgrade from ZD1100 , the status"Failed to upgrade AP04 image from [126.96.36.199.17] to [188.8.131.52.32]". Although, the version is 184.108.40.206.0.216 on this photo, but the situation is the same one. And I have try to directly upgrade to 220.127.116.11.53, but the ZD1100 alerted, the upgrade package is applicable to (18.104.22.168, 22.214.171.124.0)
You can't upgrade directly to 9.10 you have to respect upgrade path or you will loss configuration. 126.96.36.199 -> 9.9.1 -> 9.10.2 ZF7982 are supported in 9.10.2 it should works well. These "fail to upgrade" messages are weird, you should open a case for that.
