Prior to version 4, it's possible to copy/paste wiki markup to a different confluence installation, even with different confluence versions. All the attachment can be easily downloaded / uploaded via Zip Upload.
What's the solution for version 4 now?
I tried to simple ctrl+c and ctrl+v, the text content was copied over correctly, but the images were copied over as a link to old instance, which breaks.
More specifically, the attempt was done from version 4.1.7 to 4.3
