Our hosting, internet, intranet and email have been with a hosting company.
We've recently upgraded to a new building with a T1..Yay!
And are in the process fo moving all systems internal...
I've moved the internet and intranet in house already, works great.
Our domain is registered and pointing to our host provider.
Our active name servers are at our hosting provider.
I also have our http and sub domains pointed to our in house web server.
Our email and mx is still pointed to the host provider.
What I want to do....
Is move our email server and everything else in house.
How do I do it....
How do I setup the OSE so that all I have to do is change the location of the name servers and MX to get it working with minimal downtime?
Do I enter the actual (to-be active) domain mx names?...just as if it was going to be. Or do I enter a temporary domain mx name, then change it to make it live?
If I use a temporary or the actual domain mx names, will I be able to test it before it becomes live? Or will I have to hold my breath till propagation completes to know/what/how successful my setup was?
I'm nervous about this move, it's about 30 email addresses, any input/support is good!
