To determine your upgrade path:
- Use the Tested Configurations document to determine supported upgrade paths for major releases.
- Verify whether you can upgrade directly to the target release or whether you must first upgrade to a previous release before moving to the target release.
- Evaluate the complexity of your upgrade based on the number of modules implemented, number of integration points, number of interfaces, total number of business process scripts, and number of customizations to include.
- Determine the metrics and cost associated with each aspect of the upgrade.
