WLC 4400 to 5500 Migration

We have a single 4404 that was setup long before I arrived with Guest networks that timeout and other such tweaks.  Is there a document somewhere that shows a way to migrate the old settings to a new 5508 that we are purchasing?  By the time the 5508 arrives I will have a very small window to setup the unit before a new wing goes live.  I need the new unit as we have reached our limit of licensed AP's on the old 4404.  It seems like everyone keeps talking about an easy way but no one says how to do it.

Sorry, I have never setup one of these units before from scratch so I don't know how long it will take.

Thanks for your input,

Todd

Hi,

As mention before it is not recomended to upload configuration files from the 4400 WLC to the 5500 WLC since they are different platforms and they support different options.

"Do not download a configuration file to your  controller that was uploaded from a different controller platform. For  example, a Cisco 5500 Series Controller does not support the  configuration file from a Cisco 4400 Series or 2100 Series Controller."

The best option would be to configure the new 5508 with an IP address on the same subnet as the exisiting 4400 WLC, then configure mobility between them and finaly transfer the APs from one WLC to the other.

There's quite a few threads on this with the easy answer.

What version of code is on the WLC 4404?

If it is the same as what is on the new 5508 you can simply TFTP copy the config from the 4404 to the 5508 and modify the IP settings if needed. You'll want to verify the settings of course as some things (like AP manager) work differently.

The existing 4404 is running 7.0.116.0

The new 5508 has yet to arrive.

Just put 7.0.116.0 on the 5508 when it arrives and copy the config over via TFTP. Then if the 5508 is going to be online at the same time as the 4404 just change the IP of the 5508 interfaces and you should be able to have them both online and migrate fairly easily.

hello Blakekrone,

what about if 4400 running the software version  5.2.193.0

and new 5500 will have the  version of 7.0 code than how we can migrate them?

espacially in live envoirment when most of the users are connected to the ap through 4400 series contrl and working?

by the way what do you say if we upgrade 4400 series code from 5.2 to 7.0, will the changes or bugs in configuration be happen after upgrading the code?

#4400 and 5500 are different platforms. At config level you will see different no. of ports, AP-manager, Passive client,.... Backed up config of 4400 should not be uploaded to 5500 and it is not cisco suggested practice.

http://www.cisco.com/en/US/partner/docs/wireless/controller/7.0MR1/configuration/guide/cg_managing_ctrlr.html#wp1063850

Configuring the same manually is the best practice.

If you've more controllers that needs migration then compare the config between 4400 and 5500 that look dissimilar and edit it manually and port it to target 5500 WLC.

Few Tips:-

#4400 doesn't support 7.2 while 5500 does, you can use the 7.2.110.x(MR1) which is recently released for 5508.

#Also, 5508 needs FUS update to avoid critical bug.
