About reason to migrate to Deployment Solution 7.5
ITMS 6.x Migration
Deployment Solution 6.9 is a standalone product and is not designed to be integrated with Symantec Management Platform. Deployment Solution 7.5 lets you integrate standard deployment features with Symantec Management Platform.
Deployment Solution 7.5 contains the Deployment plug-ins on the client computers to execute the deployment-related tasks. The installation of the Deployment plug-ins is rolled out as a policy by Notification Server, and must always be in enabled state for a task or job to execute successfully on the client computer.
Though Deployment Solution 7.5 supports most of the features of Deployment Solution 6.9, you cannot migrate jobs and tasks from version 6.9. You have to manually recreate the supported jobs and tasks.
