Migrate Jenkins Master and Slaves Nodes

[Ashish Yadav]

I need to migrate the Jenkins Master server and Slave servers to new infrastructure. What is the ‘best practice’ to perform this migration other than just copying the JENKINS_HOME directory? What other ‘critical’ files need to be migrated over?

Considering that Jenkins stores all the configuration there, it is a solution that will work.

Regarding slaves, there shouldn't be any useful information at all. All you should do is update node settings to point to new servers.
