You shouldn't need to, I upgraded my whole dozen strong collection
including every generation of Raspberry Pi, from Stretch to Buster, and
didn't loose any of them.

When promoting a card to a later machine, I've occasionally found a
newer kernel and startX.elf isn't present, using rpi-update on the older
machine before moving the card fixes that.

I'd go for a micro HDMI cable, as I don't like the idea of a full size
cable and bulky converter hanging off a small connector. Also if you
ever want to drive dual displays, there wont be room for two converters.
