Import gadget - Aged Updates
This page lists instances in your import archive that are older instances of instances already in your target system. If you import these instances, an older instance from the import archive will replace a newer instance in your system.
In most cases, you should keep the newer instance in your target system. If you want to import the older instances in the import archive, check Import Aged Updates. If you want to import particular instances, check Import Aged Updates then deselect the check box in the Selected column for instances you do not want to import.
Select Next to continue to the next step in the import. Select << Back to return to the previous step. If you do not want to continue the import, click Cancel to exit from the wizard.
