Warning
titleAIP Backup & Restore functionality only works with the Latest Version of Items

If you are using the AIP Backup and Restore functionality to backup / restore / migrate DSpace Content, you must be aware that the "Item Level Versioning" feature is not yet compatible with AIP Backup & Restore. Using them together may result in accidental data loss.  Currently the AIPs that DSpace generates only store the latest version of an Item.  Therefore, past versions of Items will always be lost when you perform a restore / replace using AIP tools. See DS-1382.

With DSpace 6 versioned DOIs (using DataCite as DOI registration agency) were added  and the default versioned Handle strategy was changed. Starting with DSpace 6 the VersionedHandleIdentifierProvider creates a handle for the first version of an item. Every newer version gets the same handle extended by a dot and the version number. To stay by the example from above, the first version of an Item gets the Handle 10673/100, the second version 10673/100.2, the third version 10673/100.3 and so on. This strategy has the downside that there is no handle pointing always to the newest version. But each version gets an identifier that can be use to cite exactly this version. If page numbers changes in newer editions the old citations stay valid. This strategy makes sense especially if you present the version history to all users. In the image below you see a version history using this strategy.
