[Blind-sysadmins] cloning a vm virtual drive

Hello, I'm using VMware workstation and have a vm with a separate virtual drive. It is now full. What I'm wanting to do is add a new virtual hard drive, a larger one, this I can do. I'm then needing to clone the smaller drive to the larger one growing the partition size. So say a 40gb drive to a 60gb drive, the partition would be sixty gb in size. For reference this is on a Ubuntu 17.04 vm. I'd like to use Linux tools. Any help appreciated. Thanks. Dave.
