HMOL and devices upgrade

Have run a search but couldn't find anything obvious.

We are currently running HMOL version 5.1r5a and are looking to upgrade to 6.1r3.  Having never carried out an upgrade before, I am trying to find out more information regarding the upgrade process.  

Reading the release notes, they seem a bit vague. I have backed up the config and can see that version 6.1r3 is available from the software update page.  When I click on the OK button to carry out the upgrade - what happens?  Do all AP/BR devices loose their CapWap sessions?  How long should the process take?  

Once complete, I guess I have to push the update to the AP/BR devices.  How long should this take?  Is a reboot required?  Do clients connected loose wireless connectivity?    

If there is a document regarding this, can someone point me in the direction.

Thanks.

Hi Chris,

Well, I've upgraded a bunch of Hivemanager platforms and although there is no process description I'll try and write it down for you here. (I've never lost a Hivemanager config if it's any consolation :)) 

1st step is correct, I usually do a configuration backup only, so I can input it into another Hivemanager should something go wrong.

After that, you can start the update process. After you've selected your version under the upgrade menu, the following things will happen:

* Hivemanager will check if the AP's can make connection with the Hivemanager, sometimes for some reason this doesn't work. It will show that your AP's cannot make connection, I haven't found out why this is. But it's incorrect.

* After pressing accept as soon as this process is complete, Hivemanager will backup the configuration, move it to a new server. Upload the configuration in the new Hivemanager and finish the update.

* After that you will press confirm, which means you will get logged out. When you log back in, your new Hivemanager is ready.

What has happened is that the old Hivemanager still exists, but it's deactivated. Should anything go wrong, you can ask support to reactivate the old machine.

Depending on the size of the installation this process takes between 5 minutes and an hour, how big is your install?

AP's will lose CAPWAP connection to the manager for a bit, but this'll not interfere with your users.

After the update is complete you can chose to update the AP's, this will take about 3 minutes to upload and then a reboot. This will make clients lose connectivity. So it may be better to get it done after office hours (I schedule it for 00:00 in rare cases).

Is there anything else I can answer for you?

Kind regards,

Hi Stefan,

Many thanks for the reply.  

We have 63 BR's and 22 AP's, but if i err on the side of caution and go for an hour outage while HMOL is upgraded then this should be OK.

If for any reason I can't upgrade a BR or AP, will it continue to function if HMOL has been upgraded to a later version?

Cheers,

Chris.

Hi Chris,

Yes, it will continue to function uninterrupted. During the upgrade of the HMOL the AP's and BR's will remain completely operational. Only when you start with upgrading the AP's/BR's  users will be affected. The basic rule is, as long as you don't touch it, it will work as it did before :)

Cheers,

Stefan
