Hardware Upgrade: Rasperry Pi 2 to 3

Hi folks,

I just received my Raspberry Pi 3 B+, and successfully “migrated” everything from my Pi 2.
Since I installed Hass.IO on my Pi 2, it still thinks it runs on a Pi 2.
Shall I re-install Hass.IO using the install script (./hassio_install -m raspberrypi3)?
Is it necessary to tell Hass.IO that the hardware changed at all?

Cheers,
Alex
