Short answer is: NO. It is currently not supported.
You can however migrate wholer repository (inlcuding All apps, all connections etc.)
This is described well in help document.
Thank you for the confirmation. We have customers that are developing nPrinting reports on a "Dev" server then want to migrate completed work to a "Prod" server. At the moment, this process requires a rebuild of all that is in Dev. Do you know of any plans to enable the promotion of a single report project from one server to another, similar to using an .nsq in earlier versions of nPrinting?
