Checking propagating of domain name
When you move servers one of the annoying parts can be waiting for the domain to propagate when you change name servers. There is a terminal tool though for checking the settings, dig(domain information groper) is a tool for interrogating DNS name servers.
You'll need to install the dnsutils package
1$ sudo apt-get install dnsutils
After that It's pretty easy, simply put in the terminal:
1$ dig google.com
Obviously swap google for your domain name that your are checking.

A lot of people forget to plan ahead and lower the TTL for the DNS entries. Taking it down to 15 minutes a day ahead doesn't cause too much of an increase in traffic, and eliminates almost all of the transitional wait.
