update an application by blueprint
After adding an application in Brooklyn (say, by a YAML blueprint), is
there a way to update the application from an updated blueprint without
destroying it and starting over?

Makes sense to me. I agree, this is a very tricky space. I just wanted
to make sure there wasn¹t some existing approach to this that I was just
overlooking.

Hi David-
You can change an existing deployment either through effectors (e.g.
resize) or "Add Child" in the Advanced Tab -- but there is not support
for a chef-live "converge" operation to make the deployment look as if
it came from another blueprint.
I hope this helps. If you've got thoughts on how this should be done
please share them. In the general case this is a Very Hard Problem --
imagine migrating from MySQL to Riak, or having software run as a
different user -- but I think there is scope for investigating this in
some cases, maybe proposing the list of operations which will effect the
changes and running them.
