Change IP of Philips Hue bridges - what happens with my flows and devices?

Hi! I already did a search for this here but I could not find an answer. Right now I have a Homey Pro running fine connected to 2 Hue bridges and I have setup several flows. Everything has a fixed IP because of DHCP reservations in my router.

Now let’s say I change my router or network configurations and now I assign other (fixed) IP’s to my 2 Hue bridges and Homey. What happens with my flows and devices on Homey? Do I need to delete everything and start from scratch? Or does Homey re-discover my Hue bridges, recognises that the devices are already added and all my flows just keep working?

What are you thoughts? Thank you.
