I need to add a new site to an exisitng cluster which means a new Region and Location. Can I add then during the day without effectng the devices?
When I add a new Location do I have to re-sycnh bandwidth option and if so what is the effect on the other locations, devices?
When I add a Region , if I update the region relationship again does it effect anything?
Can I do the above in a working day
Short answer - yes. I've added regions and locations for new sites many times during busy times of day and never had a hint of any problem.
A re-sync of location bandwidth shouldn't be necessary, and won't have any noticeable effect to end users.
