There are many ways to do it. Depends on the resources you have and the method you would like to chose -
Some approaches -
1. Using Infor ION as middleware
2. Using WebServices
3. Using Remote execution utilities like PsExec
It also depends on the servers you have, the location of the LN server and target server, security constraints etc.
Unless you try to do something beyond what you have already mastered, you will never grow!
