looks like it needs at first a rebase before testing to match the develop branch

[h3o66]

Rebased. Another idea for this: Maybe we consider to do this the other way around and use the new one as a inital template and only set the variables in the serverconfig what you need.

Rebased this again to the latest develop branch and added the 2 new added servers to the PR.
