Ever since I've installed maverick to my second partition, I'm now unable to increase the size of it, although I am able to reduce the size of my snow leopard. I would like to find a software utility that would help with expanding and shifting the partition to permit it's expansion.

To further illustrate, I've got snow leopard first and am able to reduce it, but then I'm not able to pull the maverick up to allow for me to expand the maverick.

Thanks for any suggestions.

Far from here
The thread linked above has new posts, take a look at it.

Probably the easiest way is to clone your current Mavericks partition to an external hard drive with Carbon Copy Cloner(*), then in Disk Utility :

- delete the Mav. partition (select and click the "-" button)
- add a new partition ("Current --> 2 partitions")
- resize the partitions by dragging the divider between them
- click apply

Then clone your Mav. partition from the clone to the new partition.

(*) I would suggest that you then boot up from the clone to check that all is ok : hold the Option key on boot and select the clone.

I don't think you'll be able to merge the two.
My suggestion is to back both partitions up,
Delete the newer partition (Mavericks I'm assuming)
Grow the single partition via Disk Utility
Reinstall Mavericks
