The step wise document can be found in the interactive upgrade guide in the help. We created a workshop for going to CLM2011 because that was very complex. This time it is not so complex and the upgrade guide should do. More information can be found in the library using the keyword upgrade, for example: https://jazz.net/library/article/819
