Moving slaves from old master to new master

[Benjamin Kemper]

Hey,

I want to setup a new master (on a different url), and am looking for a way to add all the slaves that were in the old master automatically to the new one.

I have lots of windows slaves, configured as a service, which stores the master url and port in a local xml. 

This raises the following questions:

1. How to update all these slaves configurations? 

2. If I setup authentication and authorization on the new master, I'll need to also setup the new secrets on those slaves. How is this possible?

Would love any ideas to automate this besides going over 100 machines and doing this manually...

Thanks in advance,

Benjamin.
