Migrating devices - Power and Ground on I/Os?

There are no spreadsheets available, you'd have to make those yourself. Altera doesn't do it because there are too many combinations between all of the devices. The best way, and sure way to get it right, is to use Quartus II. Just make a simple project with minimal I/O pins, choose a device and add all of the migration devices you want. Compile the project and you'll have a <project_name>.pin file with all the user available pins shown as GND* or GND+. The power and ground pins will be defined as well. There's your migration compatible pin list.
