Cyclone 10 LP 10CL025 to 10CL006 migration

Hi ! I'm creating a PCB layout with a 10CL025 U256, and I'm wondering what will happen if I use in the future a 10CL006 U256 instead of this 10CL025 with the same PCB layout : - This migration mean...

You can add a migration device in the Quartus project settings. Then in the Pin Planner, it will let you know if any of your current assignments will be an issue in the migration device.

    Thanks for answering ! I'm already sure that my QSF pin assignments is not an issue because I will not use the IO pins lost in 10CL006 U256 (These pins are connected to GND 1.2V or 2.5V with 10CL025) : I put all these pins in QSF as inputs with no weak pull-up.

    I need "a confirmation that the 10CL006 FPGA will not have an abnormal behaviour with power voltage on these inputs located in the forbidden zone (between Vil and Vih) : as no FlipFlop (and consequently no CLK rising edge) are connected to these inputs, it should be OK ? No metastability or something else wrong ?"
