You need to move the location of a repository.
It is not possible to manipulate the path that a configured repository points to. In order to move to a new repository location you would need to add a new repository and update all jobs to point to that new repository.
When deleting the old repository remember to select to not delete the savepoints, as this will give you all the old savepoints to use for restores until enough savepoints are generated in the new repository.
