Hi,

we are planning to upgrade to Keyloak 22 but we are still using older keycloak adapter which is already deprecated. Can we just use latest keycloak without changing any code in the service ?  
Anyone tried it or does anyone knows whether it could work or not?

The answer to this will depend on your specific use case and just how old the adapter is. My general advice is to try it before you upgrade.
