Any advice on making the swap from ST to HA?

Hi everyone. I know there on tons of posts on the old sites threads about the mechanics of swapping from smart things to HA. Just wondering if you all have any advice on other things that might come up?

I'm about to move in to a new house. I have an instance of HA working on a little pc. I have tons of smart bulbs connected to ST, hue and others. My wife is an angel, so I probably have a good amount of time to get this right, but I also want her happy lol.

Anything I should look out for? Any personal nightmares of making your own swap? Thanks
