Device Migration - does it work with some power pins not connected?

I have a design which was originally for an EP4CE40F23, and now I want to migrate to EP4CE55F23. I can compile the design correctly (i.e. I am not having used any I/O pins which are not available in ...

Hello,

I believe you still have to connect to VCC/VCCINT/GND etc.

Thank you.

    Hello,

    I am unable to validate that based on other company's device. I would recommend you to refer to our FPGA handbook/device datasheet on your design.

    Thank you.

      I have verified and the power pins in the EP4CE55F23 are internally tied together. I have soldered one device on a board designed for a EP4CE40F23 and confirmed it's fully working! (It's not good practice, though. I think I'm going to make a redesign of the board which feeds all power pins, though. This is also what the "Migration Assistant" yields as connections, if you select EP4CE40F23 as base device and EP4CE55F23 as migration device).
