The best feature I could ask for would be a backup/restore feature.
You would have 2 servers. Old server, and new server. You would hit the backup button on Old server, and this would backup a list of everything you have installed, and all of the configurations for the apps it installs. None of the data that the apps gather, but just the configs.
The new server would restore the file that was downloaded from the backup. This would leave the servers, pretty much identical, assuming youve already migrated the data to the same paths.
This would be extremely complicated...

To be fair, that's not necessarily a good "excuse", but the reasoning is basically that each application has a completely different migration mechanism, if any, and any slight problem with user permission (or re-creating them on the target) the user could introduce while moving data, or having incomplete data would cause a problem. This would something that I don't think anyone would want to support. We're considering introducing "application files" mentions in the documents and links to migration steps, but that's as much as I think we can offer for now. Whenever that is complete, this might be a nit more achievable.
