It's always best to update to the next version of your product after you have completed work on your current project.
Some Adobe products, such as Adobe Muse, Lightroom, Adobe Premiere Pro, and After Effect, convert your files when you open them in the next version of the product. While this conversion is required to successfully use your files on the latest version, very rarely things can go wrong during this process.
For example, your files could get corrupt, or you need access to features that are no longer available in the latest version. A backup copy of your files helps ensure that your work continuity is not disrupted until you troubleshoot issues with the latest version.
When you install the latest version of a product, the previous version is uninstalled by default. To prevent the default uninstall deselect Remove Old Versions from the app Update dialog.
You can uninstall the previous version after you confirm the latest version to work seamlessly with your current workflows.
Additional work post-upgrade can include the following:
- Reinstall third-party components such as widgets, plug-ins, and extensions.
- Migrate/recreate product customization such as preferences, workspaces, and keyboard shortcuts.
If you find third-party components to be incompatible with the latest version of a product, check with the company that sold you the components.
