[Puppet Users] Migration with Puppet -- A way to profile machines for module creation?

Hello all,

We are in the process of moving our data center from one city to another city (far away). This won't be a physical move -- we are simply bringing up equivalent machines in the new location and then configuring them to match. Great job for puppet, right?

My question is, other than manually going through a machine to find all applications, versions, config files, services, etc., does anyone know of a tool that does a good job of gathering that information. The idea would be to build puppet modules based off of that.

I'd like to avoid:
rpm -qa >> installed packages.txt

There is definitely an opportunity to discuss each machine with a subject matter expert, which will be a primary step, but I'd like to come to that discussion with some information that we can filter through.


Many thanks,
Jason

Hi Jason,


I've not used it (yet) but a tool I was researching for just this need
today can be found here: https://github.com/devstructure/blueprint

I suspect there are others on the list who have used this tool and could
provide you with some feedback on it…
