I have and old Raspberry 1 B+ with a normal SD card (60 GB), then I purchased a new Raspberry 2 with a 60 GB microSD card. I have followed this tutorial to completely migrate the Raspbian OS and its data to the new microSD card, but doesn´t cover my needs since I have one microSD, and one normal SD.
The other problem is that, according to one partition software, the old SD card has 60.00 GB, and the new microSD has 58.24, so I can not create an ISO file and replace it using Win32 Disk Imager (it says that it has not enough space).
