Explanation

Why can't I clone my Lightroom CC catalog to a new hard drive or computer?

Lightroom CC on desktop does not use the drive name or drive letter (Windows) when storing paths to photos. It uses unique identifiers associated with the physical hard drives. This gives you the ability to freely change the hard drive names and volume letters without causing broken file paths in the Lightroom CC app. This is especially useful for Windows users who store their originals on an external volume that is frequently disconnected and reconnected.

Therefore, cloning your Lightroom CC catalog or user folder from one hard drive to another doesn't work. Even though you have the correct files on disk, the file paths stored in the Lightroom catalog database still points to the unique hard drive identifier of the previous hard drive.

Solution

It is recommended that you perform the following steps to resolve the issue:

  1. Quit Lightroom CC.

  2. Back up of your local originals.

    Pozor:

    If you have originals on your hard-drive that are not synced to the cloud, it is recommended that you back up your 'Originals' folder before proceeding to the next step.

    (Windows)

    To back up originals on a Windows computer, do the following:

    1. Navigate to: C:/Users/[user name]/AppData/Local/Adobe/Lightroom CC/Data
    2. Inside the Data folder, look for a folder with a long name made up of random letters and numbers (for example: '1c1fad228a024c1987b5f82737c1b293'). Open this folder to find a folder titled 'originals'.
    3. Copy originals folder to a new location outside the Data parent folder.

    (Mac)

    To back up originals on a Mac, do the following:

    1. From the Finder menu, choose Go > Go To Folder and type ~/Pictures/Lightroom Library.lrlibrary
    2. Control-click the Lightroom Library.lrlibrary file and choose Show Package Contents from the menu.
    3. Inside the bundle, look for a folder with a long name made up of random letters and numbers (for example: '1c1fad228a024c1987b5f82737c1b293'). Open this folder to find a folder titled 'originals'.
    4. Copy originals folder to a new location outside the bundle.
  3. Delete your local Lightroom CC catalog.

    (Windows)

    Delete the Data folder at: C:/Users/[user name]/AppData/Local/Adobe/Lightroom CC/

    (Mac) 

    Delete the bundle Lightroom Library.lrlibrary at: ~/Pictures/Lightroom Library.lrlibrary

  4. Relaunch Lightroom CC.

    Wait for your catalog to sync from the cloud.

  5. If necessary, import any originals (backed up in Step 2) that were not fully synced to the cloud. See Add photos.
