3600 Controller upgrade path

Looking for advice with an upgrade of hardware. Currently we have 3 3600’s in a master/local/local setup with ap-65 and ap-105 running 6.2.1.8. We are replacing the 3600’s with two 7205’s and the ap-65’s with iap-205’s, keeping the ap-105’s. What is the best upgrade path?

 

Assuming there is an AOS that supports the ap-65 and ap-205 upgrade to that version:

Upgrade the 3600's to interim AOS. Something that supports 65 and 205 AP's, 3600 and 7205 controllers.

Install one 7205 as a redundant master

Install the other as one of the locals.

Create new profiles for each building that places the AP's on the new local.

Migrate the AP's to the new profiles.

This will allow us to replace the 65's whenever we want and speed up the migration off of the 3600's.

Remove the 3600's

Upgrade to final AOS.

http://community.arubanetworks.com/aruba/attachments/aruba/unified-wired-wireless-access/14802/1/7200%20Lab%20Guide_v1.1.pdf this seems to support this idea, but I was sure I read/was told that only a specific code version supported the ap-65 and iap-205.

 

If that is not possible then:

                Create a new master/local with the 7205.

                Migrate one building at a time, replacing the 65’s with 205’s and use the DHCP scope option to point the iap-205 and ap-105’s to the new controllers (currently we use DNS. I believe the DHCP option will override the NDS name).

Re: 3600 Controller upgrade path

The IAP205 require AOS 6.4.1.x and up and the AP65s can go up to AOS 6.3

So the strategy will depend on how you are planning to replace your AP65s.

You could have your existing controllers and the new controllers running in parallel .

Let's say you replace all your AP65s with AP205's in a BUILDING (not a floor) then you could point those AP205's and AP105's to the new controllers running AOS 6.4.3.x

Make sure you disable 80Mhz to avoid CO-Channel interference and also make sure that the 802.11n and 802.11ac APs work properly disable VHT

Re: 3600 Controller upgrade path

Thank you Victor, just the info I needed.

 

Can you please elaborate a little on your last sentence "Make sure you disable 80Mhz to avoid CO-Channel interference and also make sure that the 802.11n and 802.11ac APs work properly disable VHT".

What is the importance of disableing 80Mhz and what is VHT?

I suggest you read the Aruba VRDs for 802.11ac

And the 802.11ac migration guide
