This information is the basis of the migration plan. You can develop and document migration plans in a variety of ways; the following is an example of one method.

7.9.1 Example of a Migration Plan

The Organization

Acme is an organization with a total of 30,000 users. 16,000 are allocated a fixed workstation, 3,000 are laptop users, and 11,000 access applications in Kiosk mode. The network environment is Microsoft Active Directory, and Novell SecureLogin version 3.5 is currently implemented. All users are managed from one administration workstation. ZENworks® is used for application distribution and deployment generally occurs overnight.

Sales OU users have laptops for mobile access to the network. The Central Administration OUs contain a combination of static workstations and laptop users. Manufacturing and Purchasing OU users are mobile; workstations are accessed in Kiosk mode. Users in the remaining OUs are each allocated a workstation for their sole use.

The Java functionality provided by the new version of Novell SecureLogin is eagerly awaited by users in the Sales group, so they have volunteered to test the upgrade. After the upgrade is successfully deployed to the Sales group, Novell SecureLogin is deployed in stages to the rest of Acme.
