Today’s Question: How can I move my photos to a new hard drive without losing their connection to the catalog in Lightroom Classic?
Tim’s Quick Answer: The two best options are to either move all photos to the new hard drive within Lightroom Classic, or copy the photos to the new hard drive and then update Lightroom Classic to reference the new location. In either case I recommend making sure you have an updated backup of all photos before getting started.
More Detail: When you want to migrate photos to a new (and presumably larger) hard drive in Lightroom Classic, the most important thing is to make sure you don’t cause the folders and photos to go missing in the context of your catalog. I also highly recommend making sure you have an updated backup of all photos before you begin the migration process.
One option is to move all photos to the new location from within Lightroom Classic. However, this can be a more time-consuming process, so it isn’t what I recommend when you’re moving a large number of photos.
Instead, I recommend copying all folders and photos to the new hard drive. If you maintain the exact folder structure hierarchy as part of this process, you’ll streamline the overall process. For example, after copying all folders and photos to the new hard drive you can rename the volume label (Macintosh) or update the drive letter (Windows) to match the old drive. This would mean that the new hard drive appears to be exactly the same as the old hard drive, so no folders or photos would appear missing after the change.
If you want to make a change to the overall storage structure, you can also update the folder location after copying all folders and photos to the new hard drive. For example, let’s assume your folders are all stored in the top (root) level of the hard drive but you now want them to all be contained within a folder called “My Photos”. You could create the “My Photos” folder on the new drive, and copy all folders and photos to that location. Then, in Lightroom Classic, you can right-click on the top-level folder that is missing (which might be the overall hard drive, for example) and use either the Find Missing Folder or Update Folder Location command to connect the catalog to the folders and photos in the new storage location.
