Q for gurus:

In the process of switching my home network from *.local.lan to <realdomain>.com with pfSense router. I have some local services running on <realdomain.com> using DNS host overrides, and intend to supplement with some cloud services in the future.

There are 100+ devices on local.lan and I expect many things to break when I switch to <realdomain>.com.

Is there a clever way make the change slowly so that I'm not chasing down many problems all at once?
