After you’ve completed the installation of SBS 2011 into your SBS 2003 network, you have 21 days to complete the migration and decommission the original server. There are several steps in the process—some automated, some not.
From the time that Windows Small Business Server 2011 Standard is first installed and running on your existing SBS network, you have a maximum of 21 days to complete the migration. Required tasks listed in the Migration Wizard must be completed in the order listed. Optional tasks can be completed later because the other tasks in the task list are not dependent on them. The tasks in the Migration Wizard are listed in Table 7-2.
