I want to move or copy Jenkins from one server to another. Is it possible? If yes, how?

Copying the Jenkins jobs directory from the old server to the new one is a good idea. We can easily migrate a task from one Jenkins installation to another by simply copying the job directory.

We may also create a duplicate of an existing Jenkins task by cloning the job directory and renaming it.

Another option is to rename an existing task by changing the directory name. If you rename a job, any other job that attempts to contact the renamed job will need to be renamed as well.
