Goal: To perform a quick LUCS update
Complexity: Medium
Preconditions:

  • This scenario explains the upgrade procedure with 2 systems up and running. Make sure that one server is active (in this example Server 1 (red star)) and one server is passive (in this example Server 2 (blue star)) as redundant system. 
  • LUCS Server and Credentials are known
  • Admin / DB access rights on all machines are given
  • Installers for new LUCS version are held ready, copied to both systems
