What to upgrade first for smooth Transition

[R Shaik Mahamood]

We are trying to upgrade Prime, MSE and WLC to the latest code. But need to figure out what to upgrade first. Is there a procedure to follow? Checked the compatibility chart and Upgrade guides but did not find specific info. Please advice

The Release Notes for each platform have detailed instructions on how to perform an upgrade successfully.

[Sathiyanarayanan Ravindran]

You have to check the release notes of the WLC, Cisco Prime and MSE, Based on that you have to take a decision.

Refer : Cisco Wireless Solutions Software Compatibility Matrix

For an example if you are upgrading your prime with 3.6 Code, your controller code support will be as per the Table 6 Cisco Prime Infrastructure and Cisco Wireless Release Compatibility Matrix based on the model of your WLC.
