I little later I was wanting to test (and possible do a permanent) change in the main multisite domain name that has Pro Sites.
1. If I change the name will all subsites auto adjust and have no breakage or issues?
2. Where is the best link for best practices to do the change (checklist of sorts etc) that will enable a smooth change? There will only be a handful of subsites by the time I decide to play with doing it by the way . . .
3. If I decide to abandon changing because of one reason or another or there becomes issues, if I change it back with it easily restore functionality?
4. Any other ideas or thoughts on this topic would be good?
5. Do you see this being done a good bit among Pro Site users for one reason or another?
6. Do you consider this pretty routine? From what I have read so far, it should be fairly easy on the difficulty scale.
