You work as the network administrator at Cer-tech.com. At present the Cer-tech.com network makes use of a Lotus Domino system for e-mail and messaging purposes. The management of Cer- tech.com decides to implement a Windows Small Business Server 2003 network with Active Directory and Exchange Server 2003 messaging system. A new Cer-tech.com management directive states that the Cer-tech.com network is to be upgraded to a Windows Small Business Server 2003 network in an Active Directory domain and using Exchange Server 2003 as the new messaging system. You received instructions from the Manager to implement the new management directive. In the upgrade you must minimize the impact on business operations that might result from the migration from Lotus Domino to Exchange Server 2003. You then decide to implement an incremental migration strategy where migration will take place in a step by step process and the users that are not migrated with the initial migration to the new messaging system continues to make use of the existing Lotus Domino system. You also need to make sure that both messaging systems function properly and that there is the successful exchange of e-mail between the users of both Lotus Domino and Exchange Server 2003 systems. What should you do?
