Reload configuration from disk - Jenkins

In case of migration of existing jobs from one Jenkins setup to another setup or removing old build information from the disk, we can use the option to reload configuration from disk in Jenkins. Below are the steps to be be followed to reload configuration from disk:

• When we set up jenkins in a machine, there is a folder with name .jenkins in location c:/users/<UserName> folder.

• When we open the .jenkins>jobs folder, we see the folders for the jenkins jobs we have created in jenkins. 

• We can copy folders from another jenkins instance and paste in this folder. Similarly we can make changes in the logs information or builds information.

• Once we have made the required changes in the jenkins set up. Open Jenkins using localhost:8080 (assuming you are on the jenkins server itself and 8080 is the port used for jenkins and is installed as a window service on the server. Else if accessing from a remote client machine, use the address <machine name>:<port number>

• The jenkins home Page will open as shown below.

• Click on Manage Jenkins and in the Manage Jenkins Page, click on Reload configuration from disk as shown below. This will reload the changes made in jenkins set up.
