You can create multiple versions of an object at any time. View the object's version number on the General tab, in the Properties window.
Note: You cannot create new versions of Style objects.
To create a new version of an object:
- In the folder list or Search Object list, select the object for which you want to make a new version.
- Right-click on the object, and in the shortcut menu select Create New Version.
- Click Yes to create the new version of the object. Author creates an exact duplicate of the original object, with a new version number (each new version has the number incremented by 1). The different versions of an object keep related to each other, as you can see in the Show Relationships window.
Once you have updated the new version of the object, use Replace object to replace the old version in all relationships.
