Tools and other forms of automation can often go a long way toward enhancing the efficiency of migrations, especially in circumstances involving large numbers of users and multiple sites. In the case of Intermedia, the company has developed a migration wizard that leverages a super-user account. "This enables our engineers to log into the customer's system and pull a copy of their Active Directory infrastructure and then import it directly into their system for the new account," said McCormick. "The tool can then pull data for each of the users, creating all of the user accounts and distribution lists. The tool can also set up mail filter redirection and simplify configuration for the cut over. We also use a single sign-on tool as well as an Outlook profile helper."
