Follow the instructions relevant to your situation:
Using the same router in a new space-
If you move your router along with your lights, it should all continue working as usual.
New router but with the exact same name (SSID) & password-
The LIFX app should still recognise the lights. You don’t have to do anything in this scenario.
New router with new name OR existing router but with a new name or password-
You are going to need to hardware reset the lights and reconnect them, just as you did the first time you set up your lights.
To add the light to the new network follow these instructions
Schedules and scenes will still work with the lights once reconnected. If you use the same light names, all other integrations should work as expected as well.
