What you want to do, can be done with a combination of parted and resize2fs. Take good backups first. It would have been easier if you were using LVM. basic strategy, resize2fs to shrink /usr/local file system, then parted to shrink /usr/local partition, then parted to grow /usr partition. The last time I did this I had to actually delete one of the partitions out of the partition table and then re-create it in the same spot. Not for amateurs.
