Any experience in Upgrading 3.4r2 to a higher version?

Hi All, 
We are attempting to upgrade the HiveManager from 3.4r2 to any higher version (on a 1U Device). This is to get the AP120's to a better firmware to support 802.11n, currently the 802.11n-draft isnt giving the desired bandwidths. 

First attempt - started the upgrade to 4.1r4; the system warns of a restart, uploads the files from my laptop to the device 100% and continues showing the updating status, after 20-25 mins the system hangs (its more like its switched off), Power LED is OFF/no HDD Activity/No ping response from MGT/LAN IP's/ LED's on the MGT & LAN Ports are Solid ON - The System never comes out of this state without a power cycle. 
After a Power cycle, the Version is still at 3.4r2, Hive operations are normal. 

We have started another Attempt this time with 3.5r4, same situation as above.
Via CLI (SSH, Console dosent work for some reason): Display Upgrade/restore progress" was showing "upload update package: 100%" and "update software files: continuous # signs".
I plan to leave it in this state over night assuming the update take very very long (have waited 5-6 hours on the previous attempts).

Kindly suggest if there is something else that can be done. 

Thanks!

There are memory requirements for versions 4 and up.  It is possible that your older 1U does not have enough memory to upgrade.  It has been MANY years since I upgraded from 3 to 4 but I do believe that was the point at which I had to install more memory.  I also had a similar issue where the install looked to be functional and then on a reboot it was back to the previous version.

I personally have issues with the 110s and 120s with code above 5.1r5.  But you can have the HM with any version before NG and still keep those APs with a lower code version.  Since the system is Controller-Less they two don't have to be on the same version.  I currently run 6.8r3 and still have those older APs on 5.1r5.1089.  Simply because the update to the 6 code started the Application Monitoring and they overheat and stop working.

Hope that helps.

Hello Fred, 
Thank you for the inputs and suggestions... It makes sense now, even a simple backup operation results in the system hanging.
We are getting a memory upgrade done, will attempt a HM upgrade after that.

I assume once i have the 120's up to version 4.x/5.x 802.11n will have a better version and we will be able to get higher throughput. 

Thanks again and will let you know the status after the memory upgrade.

Hello Fred, 
Finally the RAM was upgraded, we added 2MB more, the system is now with 3GB RAM.
Upgrade to 3.5r4 was successful and I could upgrade the firmware on all the AP120's to 3.5r4 too.
 
Some how all ChromeBooks (Samsung/HP's) and Desktops/laptops connect on 802.11g and all iPhones/Android devices connect only on 802.11a. 

Attempts to upgrade to 4.1r4 are turning up the same results as earlier.. i.e. after the upload the upgrade starts and after 15-20 mins the system goes into a hang state, no LED's on/dosent respond to ping.. 
Cant even tell if the system is doing something. 
Will leave it in this state and see if there's a change...

Thanks.
Regards

Aerohive does have band steering options available in version 4 if I remember.  I did not have any success with forcing devices to the 5ghz band.  IF you are trying to force something like that I'd suggest turning off the band you don't want them to use altogether.  Unfortunately that will remove it from being able for all devices.

I did not experience any issues upgrading to the further versions of 4 once I had the memory upgrade.  Unfortunately it has been quite some time since I worked with that version of code.
