Migrating from old WLC to new vWLC

Hello all,

I currently have 2x 3502i-A-K9 Ap's connected to a WLC-4402. AP FW is 7.0.252.0 and the WLC FW is 12.4(23c)JA10.

I recently got a Virtual WLC and have it initially configured. I would like to migrate those AP's over to it. I tried setting the new WLC as the master WLC and rebooted a single AP and waited to see if it would connect to the new one. It took awhile but didnt connect and ended up going back to the old 4402.

The vWLC is running FW 8.2.141.0. I also tried setting a secondary WLC in the AP settings to the new vWLC and a simple reboot of the AP didnt have any positive results.

How would I go about migrating these AP's over to the new vWLC? compatibility matrix says the 3500i is supported on the current VWLC firmware?

Maybe the issue is vWLC is trying to authorize APs against MIC database. You can disable this feature by using this command:

config auth-list ap-policy authorize-ap disable

Oh also, When I ran a debug of capwap, I can see both AP's send requests, but I do see a message that says:
