Controller firmware upgrade - best practise

Hi All,

I have two 7200 controller in active standby mode with vrrp configured.

I am planning to upgrade it this month. As vrrp required two controller image in same version so I am bit confused.

Shall I upgrade both the controller at once ?

HI Rana,

 

Why don't you enable centralised Image management on the Master. BTW VRRP will not get effected with Image mismatch, only Master standby will get effected.

 

Please feel free for any further help on this.

So I think first I have to upgrade backup controller and then Master right ?

HI Rana,

 

Either way will do but if you have Local controllers deployed, as a best practice upgrade the Standby first and then Master.

1. Upgrade the image of backup partition of Standby

2. Upgrade the Image of Backup partition of Master

3. Enable " AP Image Preload" if you want to reduce the down time

4. Reload both the controllers.

 

Note : don't forget to take the flash back up of the master before doing the above.

 

Please feel free for any further help on this.

Re: Controller firmware upgrade - best practise

Thanks venu for your response,

I am planning to upgrade the master controller first so all the APs will go to backup master and after that I will upgarde backup master, so again all the AP will come back to master controller.

Is it correct way ?

I dont have local controller.

Yes Rana,

 

That will work but ensure that you have taken Flash backup before doing all.
