If you're using patch management and software delivery, I would configure the patch download location to be a different location, and if need be change the software library location as well. If you change the patch location, there is a task that can be run to update all the current patch packages (move the files, change the .xml). If you move the software library, it could be a bit more tricky or at least time consuming, as I don't believe there is a migration task.
