[windup-dev] Automatic upgrading (of the whole app) discussion

[Ondrej Zizka]

Ah, here I found this post.

I am not sure about cloning. Only the rules could be potentially needed 
to transfer. And maybe the .ignore files.
Hence I'd rather swap the whole distro directories and then transfer the 
XML rules. To keep the process simple and to avoid collisions when we 
change some dir structure.

WDYT?
