Q: How long does it take to migrate?
A: It varies by organisation size and the number of servers being used but normally 1 message per user per second is a good rule of thumb. So if you have 10 client servers each processing 10 users (for 100 users) you are getting 100 messages a second. If each of the 100 users has 10,000 messages (for a total of 1M messages), migration is 10,000 seconds or 2.78 hours. As you can see for a small organization it’s pretty quick.

Q: Is their any downtime?
A: Using Google dual delivery, Google servers operate alongside your current mail system delivering mail to both systems till Gmail mirrors your old system and then the old system is turned off.

Q: What is Postini and how much does it cost?
A: Postini is an email and web security service, it filters spam and malware before the message hits the mail service. Email retention can be purchased in a 1 or 10 year increments. Costs depend on whether the organisation has Google Apps for Buiness.

Q: What security options are available with Google Apps?
A: Google is FISMA and SAS70 Type II certified. A two step verification helps further secure Google accounts. Basically, you enter your password then a verification code is sent to a mobile device that has to then be entered into the account. This way even if someone has your password they can’t access your account. (Google Apps Security, pdf)

Q: Can Google Apps support multiple domains under one account?
A: Yes, multiple domains are supported either as separate domains or domain addresses. This way you can send and receive mail to and while only paying for the Google account.
