Here we are going to talk about very basic workflow of Backup/Restore between different versions of Adobe Photoshop Elements. Every latest version of Adobe Photoshop Version supports backward compatibility for Catalogs, which means that any catalog of older versions can be reused in upper versions of Adobe Photoshop Elements. Normal Catalogs of old versions can be converted directly into newer version catalogs and if there are backups of catalogs, restore operation automatically convert the catalog for new version. Let's take an example of PSE8 backup which we want to restore in PSE10 -
1. Launch Organizer of Adobe Photoshop Elements 10.0
2. Go to Restore option under File Menu
3. Go through guided steps of locating backed up files and start restore.
Hopefully Restore in newer version works well for you. Please feel free to post any comments for further queries around specific scenario about Backup-Restore in Adobe Photoshop Elements.
