CCC Lion HD to larger Drive, Advice
It's generally a good advice not to run beta software for critical operations. Use a stable version. I use SuperDuper personally.

After cloning the drive, you should be able to just hook up the new cloned hard drive to your iMac and the computer will be just like when you cloned it. If you do any work after cloning it, the cloned drive won't have that changes.

Every Lion installation creates a recovery partition for when you want to reformat the drive or when something bad happens to your OS.

If you just clone your main hard drive partition, your Lion recovery partition will not be cloned.

This means that you will not be able to boot into your recovery partition in your cloned drive. There are a few ways to get around this, but I haven't tested this myself:


Install Lion on your new drive before you clone your old data to it.
Install Lion on your new drive and use Migration assistant instead of cloning.
