Compatibility of old Cosmos PCB with new flashchips

Hello all,

we do have an old Cosmos board with the usual Cosmos flashchips. Currently, we evaluating on upgrading to a cosmos+ Version. Thereby, we were wondering whether the old PCB is sufficient enough to be compatible with the new cosmos+ chips oder there were any changes on the board as well.

Maybe some has already upgraded his board and could share his/her experience.

Thanks,
Tobias
