Re: [PLUG] Move SD card from Raspberry Pi 2 to Raspberry Pi 4 Model B

You're leaving valuable performance on the table and future upgrade limitations by swapping out the SD card. Yes it will work because the processor can run backwards compatible byte code (thank the ARM instruction set for that).

A question closely related to my previous one...

Simple/not simple question: is it safe to move the SD card from my existing Raspberry Pi 2 (Model B Rev 1.1) to the latest-and-greatest version? The existing Pi is running Raspbian Bullseye and a 4 drive mdadm RAID 5- hence wanting to upgrade to the more capable board. I figure it's easier to move the existing SD card + drives to the faster Pi than to set up the new Pi from scratch and migrate the RAID to it. Or would it be?
