Note: If LMS site has set-up with "App to DB" encryption or added any certificates in “security” folder, Copy the "Security" folder from ibmsdk64_backup folder [<LMS application folder>\ibmsdk64_backup\jre\lib]

& Replace with latest "Security" folder [<LMS application folder>\ibmsdk64\jre\lib]

 

5. Run Install.bat (via CMD) on PE and Auto Configuration on the LMS
