On-premise Customer License: How do I replace my old c9.license file?

For on premise customers, here are instructions on how to replace your new license file.

1. Rename the license file sent to you by Knowi Support to: c9.license
2. Replace the existing c9.license file (found in ../cloud9/c9.license)
3. Restart your tomcat server

For cloud customers, licenses are managed by Knowi Support, so this can be ignored.
