Subject Re: update an application by blueprint
Date Thu, 11 Jun 2015 14:37:14 GMT

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.
