How to Move Lightroom Classic to a New Computer Without Losing a Single Edit
Updated: Oct 24
Most photographers put off a new computer for months because of Lightroom Classic. I understand why. Almost every horror story I hear about the move began with a ten-minute shortcut, and the shortcut is nearly always the same one. The photographs are copied across, Lightroom Classic is installed, and someone presses Import.
The photographs arrive safely. The develop history, the masks, the collections, the flags and the keywords do not. Years of work are still on the old computer, and the new one has no idea any of it happened.
This article explains why that happens and walks through the method I use and teach instead. I have also rewritten my full guide for Lightroom Classic 15, and it is now a free download. It covers every step in detail, with screenshots, a troubleshooting section and a Move Day Check to print.
How the catalogue works
Lightroom Classic does not store photographs. It stores a catalogue, a database file ending in .lrcat, which records where each photograph lives on disk and everything I have done to it. Flags, star ratings, keywords, collections, virtual copies, stacks, the full develop history, and every mask live in the catalogue and its companion files, not in the photographs.
That is why dragging and dropping the photographs breaks everything. The files arrive, but nothing on the new computer knows what was done to them. The answer is to move the catalogue itself, then tell it where the photographs now live.
Four shortcuts that lose your work
Every one of these has been recommended to me in good faith, and each loses something.
Importing into a new catalogue. A new catalogue sees new files, so every collection, flag, virtual copy and develop history is gone, along with years of masking work. It is the worst option of all.
Saving metadata to XMP. XMP files carry the current develop settings, ratings, labels, and keywords, making them a useful extra backup. They do not carry flags, collections, virtual copies, stacks, the full develop history or publish services.
Synchronise Folder. It removes records of the missing photographs and imports the files at their new location as brand-new photographs, with no edits and no history.
Export as Catalog. The least bad of the four. It carries the edits into a new catalogue, but leaves behind publish services and sync information, and brings no presets, templates or plugins.
Prepare the old computer first
Every broken link in the catalogue today is a problem I would meet again on the new computer, so I fix them before the move, while they are easy to find. Choose Library > Find All Missing Photos and Lightroom Classic gathers everything it cannot find into a temporary collection.
I work in a fixed order. I work in a fixed order: drives first, then folders, then individual photographs. Relinking a parent folder repairs everything beneath it, so starting with single photographs creates far more work than it saves.
Drives. On Windows, a portable drive can arrive as E one day and F the next. I give every photo drive a fixed letter from the end of the alphabet in Disk Management, usually Q.
Folders. Right-click the highest missing folder and choose Find Missing Folder, then point it at the folder's current location. Every subfolder relinks with it.
Photographs. Click the exclamation mark on the thumbnail, choose Locate and tick Find nearby missing photos so the rest of that folder relinks at the same time.
Next, I gather the library under one root folder on each drive. Show Parent Folder in the Folders panel adds the level without importing anything, and folders dragged inside Lightroom Classic move without breaking a single link. One root folder means the whole library copies in one operation and relinks with one click on the new computer.
Finally, a fresh catalogue backup. In Lightroom Classic 15, the backup settings have their own Backups tab in Catalogue Settings, and each backup is saved as a .zip file.
What to copy
I copy everything to a fast external SSD, which turns an afternoon of copying into an hour. When moving between a Mac and a Windows computer, I format the drive as exFAT first. A Mac can read an NTFS drive but cannot write to it, and Windows cannot read a Mac APFS drive at all.
The photographs. Copy the root folder as-is. An untouched folder structure is what makes the relink a single click.
The whole catalogue folder. Quit Lightroom Classic and copy the folder, not individual files. That is the only way to be sure the .lrcat-data file travels with the catalogue, and that file alone holds the AI masking and People data.
Presets and templates. The Presets tab in Preferences has buttons that open both preset folders. Copy them to the transfer drive.
Plugins. File > Plug-in Manager lists each one. I note the licence keys and download fresh installers for the new computer rather than copying old plugin folders.
If you use the Lightroom mobile app, check for a Mobile Downloads.lrdata folder beside the catalogue. Photographs synced from your phone land there, and they are easy to forget. I move them into my normal folders before the move.
On the new computer
Install the Creative Cloud app, then Lightroom Classic. Not Lightroom, which is the cloud-based application.
Copy the catalogue folder and the photographs into place. The same locations as before keep things simple.
Double-click the .lrcat file so Lightroom Classic opens your catalogue instead of creating an empty one.
Right-click the root folder, which will show a question mark, choose Find Missing Folder and select the root in its new location.
Lightroom Classic relinks the root and every folder beneath it, and the edits, masks, collections and history are all there. Then I copy the presets back, reinstall the plugins and set up backups before editing anything.
I keep the old computer working and untouched until the new one has run for a week without surprises. It is the only undo button this process has.
When something looks wrong
Almost everything that goes wrong after a move has a one-line fix. These are the three I see most often.
The library looks out of date. Lightroom Classic has opened the wrong catalogue, often a backup. Use File > Open Catalog and choose the one you copied.
Masks have disappeared. The .lrcat-data file did not travel with the catalogue. Copy it into the new catalogue folder next to the .lrcat file, then reopen.
Previews take hours to appear. They weren't copied, or they're being rebuilt for the new screen. It is not a fault. Let it run overnight.
The full guide covers eight problems, including drives that will not accept files, missing presets, and broken watermarks.
Download the free guide
Moving Lightroom Classic to a New Computer is a free 27-page PDF, written for Lightroom Classic 15.0 to 15.6 on macOS Sonoma or later and on Windows 10 or 11. It follows the method above in six sections, with the exact menu paths for both operating systems, a Quick Reference of every file to copy and where it lives, and a one-page Move Day Check to print and tick off on the day.
Download it, print the Move Day Check, and keep it beside both computers on the day.
How do I move it if I have to cloud or classic software available on the new system?
