Establishing a Baseline
A baseline is required for exporting to a synchronized system, but not for exporting to a selective system. The baseline determines the point from which changes are tracked. For synchronized systems, the baseline should be established when the two systems are still administratively identical, such as immediately following a cloning activity using the Windchill Rehost Utility. The command to establish a system baseline should only be run once.
