To make minor changes to an existing agreement such as changing the payment terms, you can simply update the existing agreement and save your changes.
However, if significant changes are required and you want to track versions of your changes, you can create a new revision. When a revision is created, a new version of the original agreement is created. This is useful for tracking and managing multiple
versions of the same agreement. You must determine when changes warrant a new agreement version, and then you can
manually create a new revision with a new revision number. It is helpful to use a logical numbering sequence such as 1, 2, and 3 to number your revisions. Once the new agreement revision is created, you can update the agreement header information.

Note: You must end the current revision before creating a new revision. An agreement can have multiple revisions but the effective dates cannot overlap. Only one revision can be effective for a given range of effective dates.
