What version of code are you running at each end?
Have you gone through the guides in detail?

- Ref : https://www.cisco.com/c/en/us/td/docs/wireless/compatibility/matrix/compatibility-matrix.html , make sure software versions on the 5508 and 9800 are compatible , for that take a look at Table 1 and the column Cisco AireOS-IRCM Interoperability. There is a special for workaround for a 5508 which has an expired mic , for that look at : https://community.cisco.com/t5/wireless/inter-release-controller-mobility-ircm-with-5508-fail-control/m-p/4274202#M225325 , (wait a few seconds until the solution-part of this particular thread appears on your screen). Always useful is to have a configuration review of the 9800 CL too) with the CLI command : show tech wireless , have the output analyzed by https://cway.cisco.com/tools/WirelessAnalyzer/ , please note do not use classical show tech-support (short version) , use the command denoted in green for Wireless Analyzer

CIsco 5800 is 8.10 and cisco9800 CL is 17.08.01. Yes, they are compatible. Cisco 9800 is virtual image

@nareshgatta1986 5800? No such thing as far as I know. Presume you mean 5508 as you said in the initial post?
5508 cannot possibly be running 8.10 because the last release to support 5508 was 8.5. 8.10 does not support 5508!
So do you want to check that answer? And provide the exact release which the 5508 is running?

With C9800-CL, you need to configure the hash value in 5508 mobility configuration. If you are using IRCM compatible code version pls check that setting as explained in below
