During an upgrade, if AA is selected then it copies all files and registries related to the Advanced Authentication feature.
NOTE:
After upgrading SecureLogin, the re-authentication method needs to be the same as configured for the Advanced Authentication feature. To ensure this, navigate to Edit Wizard > Re-Authentication and select the appropriate logon method.
After upgrading SecureLogin, the older 4.x interface to connect to Advanced Authentication 4.x server is displayed along with newer interface. To resolve this, the user needs to uninstall the 4.x SecureLogin Advanced Authentication plugin and use the latest interface which connects to 5.x Advanced Authentication server.
