Enabling Staging and Export/Import

Your Guestbook application creates guestbooks and entries that are immediately published when they’re saved. Sites constantly change, however, so it’s crucial to have an area where updates can be planned and tested before publishing to your audience. Staging enables changing your Site behind the scenes without affecting the live Site. When you’re done, you can publish all the changes at once.

Next, you’ll implement Staging support in your Guestbook app so its entries can be tracked during the Staging phase of your publishing process.


Figure 1: Once Staging is implemented in your Guestbook app, you can have its data tracked by the Staging framework.


Figure 2: A Staging-enabled Guestbook app can be modified on the staged site first without any users seeing it on the live Site.

Export/Import facilitates extracting data so it can be imported into another Liferay Portal installation. Behind the scenes, Export/Import is used during the Staging process. When publishing your staged content to the live Site, you’re essentially importing content from the staged Site and exporting it to the live Site. Since the Export/Import framework is programmatically similar to Staging, you can implement it with Staging.
