Hi guys!
I got a question from a colleague if it's possible to create a copy of a message broker in order to scale with another broker. My initial gut feeling tells me its not possible without creating a new one and deploying the same flows to it.
The best option would be to create an exact copy except from the broker uuid, QM and Broker name, but something tells me its not that easy?
Any good alternatives that I dont know about?

It's exactly that easy. An exact copy except for broker uuid, QM & broker name is a new broker with the same flows deployed to it! 
This is the best and only realistic option. It's certainly far quicker and simpler than copying the file system/database, editing the details in some way I can't imagine, and then getting the config manager to adopt it.
New broker, quick & cheap. Deploy the existing flows, quick and cheap. Peace of mind, priceless.

Hmm, reading my post again it seems that maybe I wasn't specific enough..
New QM in same cluster - easy
Creating a new broker - easy
Deploying 100+ flows with the same version - quite a hassle
I was hoping for a way to skip deploying all running flows since that's the tough part. Either by extracting the flows (which I'm pretty sure is not possible) or by creating an exact broker copy in some magical way.
So is the only option available to deploy all flows?
Thanx for the response though!

It's 1 - n deploy commands.

Why is this tough? A little script and all the bar files will sort themselves out.

I'm pretty sure you're right

Magical, if not miraculous. Unless some passing IBMer has a suggestion.

It's my preferred option certainly.

It's one deploy operation.
Or at least, one deploy operation per EG.
You don't need more than one BAR file per EG.
granted, it would be nice to have a tool that would merge bar files... At least, so hurworti keeps reminding me. |

I was assuming that the 100+ flows the poster mentioned had been built up over a period of time from a number of bar files. Of course, if the relevant code can be packaged in a single bar because the source code identification is so good then wonderful, but if that was the case I doubt the question of extracting bar files would have come up....
