Both admin-level and user-level personalizations may be extracted from one database and loaded into another. This allows you the freedom to create and test personalizations in a test database before deploying the personalizations to a production instance. Use the Import/Export UI in the Functional Administrator responsibility to deploy your personalizations.
Note: While the Import/Export UI and command line tools are not applicable to Online Patching introduced in Release 12.2, they will continue to work in the presence of Online Patching. Refer to Section 6.3 in Deploying Customizations in Oracle E-Business Suite Release 12.2, My Oracle Support (formerly Oracle MetaLink) Document 1577661.1, for additional steps on how to deploy your custom personalizations via a patch in conjunction with the Online Patching feature.
