I'm currently upgrading my Jenkins by installing a fresh Jenkins on another hard drive. The old Jenkins has a bunch of projects in folders using the plugin.

I cannot move the jobs directory to the new Jenkins (about 600+GB of data) so instead I am trying to point to the old Jenkins jobs directory. The way I am doing it is to modify the 'Build Record Root Directory' path.
Example: /home/user/jenkins_old/jobs/${ITEM_FULLNAME}/builds

${ITEM_FULLNAME} is a variable that represents [folder_name]/[project_name]
However the folder plugin creates an extra jobs directory in between the two.

I cannot get my new Jenkins to point to: /home/jenkins_old/jobs/[folder_name]/jobs/[project_name]

Could this be changed so that the jobs directory in between the folder and project does not exist?

This would allow for a much smoother process when trying to upgrade to a fresh Jenkins.
