Expanding a converted Hyper-V to VMware disk

We recently moved out of a Hyper V environment to VMware.  I was able to convert all of the Hyper-V virtual servers to VMware VM's without any issues.  All of the servers that I converted that were 2008 servers and earlier allowed me to expand the disks size as long as the server was shut down.  All of my 2012 Servers will not allow me to expand the disks powered on or off.  Is there any solution to this other than creating new servers?  I have the C: drive of one of these servers that was created with a small amount of drive space -(prior to my arrival)- this is an application server and would be a very in depth process if I have to re-create it.  Only issue I have is the space on this one drive.

Any solutions would be greatly appreciated.

You should be able to expand the disks.

The process, is

1. expand the virtual disk.
2. expand the OS partition.

The GParted solution was a great thing to learn although it would not resolve the issue.  The trick was removing the disks from the VM and adding to another- resizing- deleting and adding back- brilliant but I feel like I should have thought of that myself!! LOL
