Either Disk Utility, or my choice would be Carbon Copy Cloner (it's free). Install your new drive in a spare sled, partition and erase it (use GUID format partition map) and clone with CCC. Make sure the drive is named something appropriate before you do this process (eg New Drive). Then reboot holding down the Option key, and Bob's your uncle.
