Learning how to move Lightroom to a new computer might sound like a scary proposition to many photographers. But, since we change computers every three to five years, it is unavoidable. That is why I treat it as part of my photography workflow.
First, I do not treat my Lightroom setup as a monolith installation; it is more like a multi-piece entity with its parts scattered across different corners of my computer.
Let me explain.
I keep my Lightroom installation with the master catalog, configuration files, and previews on my primary SSD (solid state drive) hard drive. It is extremely fast but relatively small at only 500 GB. This means that I cannot store my entire photo library (a total of 5 TB) next to my master catalog.
I have a conventional hard drive (8 TB) dedicated to my photo library.
Finally, I keep my Lightroom catalog backups on a separate hard drive where I store all my archived files and the resources I do not use on a regular basis.
I treat the process of migrating Lightroom to a new computer as a multistep process where I address the different parts of the Lightroom setup separately.
How to Move Lightroom to a New Computer
The process of migrating Lightroom to a new computer can be broken down into seven components, two of which are optional.
- Lightroom Installation
- Photo Library
- Lightroom Catalog
- Configuration and Settings
- Re-link the Missing Folders
- Preview Files (optional)
- Catalog Backups (optional)
When you address each component separately, the whole process becomes very logical and uncomplicated.
Step 1: Install Lightroom
Before you can install Lightroom, you must install the Creative Cloud application on your new computer.
After installing the Creative Cloud app, you must authenticate it using your Creative Cloud credentials.
Next, deploy Lightroom by triggering the installation from the Creative Cloud app.
As you probably know, Creative Cloud allows you to install Lightroom to two different computers (Mac and PC). If you have already installed and activated Lightroom on two computers, you must go to the Creative Cloud web portal (Plans & Products tab) and disconnect one of your installations.
TIP: Make sure that you do not disconnect the computer from which you are currently performing the migration. You will need to access it multiple times throughout the migration process.
In my case, I have Lightroom activated on my desktop and on my travel laptop. When I start the migration process, I deactivate my laptop installation so that I can use Lightroom on my old and new computers during the migration.
Step 2: Migrate Your Photo Library
Before you start moving your photo library to a new computer, make sure it is well organized.
This organization style makes it incredibly simple to back up your photos. It also makes it easy to move your entire library from one location to another.
If your photos are scattered across different drives and directories, you will have a hard time managing your library.

Before starting the migration, I strongly recommend that you conform your photo library into a one-directory structure.
TIP: Make sure to organize your library from within Lightroom using the Folders Panel in the Library Module. If you use Explorer (Win) or Finder (Mac) to move your image files around, Lightroom will not be able to track these changes.
Once your library is in order, use an external hard drive to copy your entire library to your new computer.
Step 3: Migrate the Lightroom Catalog
The next step is to move the catalog file to a new computer. The Lightroom Catalog is a database where the application stores the information about the photos and their organization.
It is not always easy to locate a catalog file because, sometimes, it is buried deep inside your computer’s installation folders. Fortunately, Lightroom provides us with a shortcut to an active catalog location.
How to Find Lightroom Catalog Location
Here are the steps to pinpoint Lightroom catalog location:
From the top menu, select EDIT (Lightroom on Mac) > Catalog Settings… Go to the General tab and click the SHOW button. This will take you to the directory where the Lightroom catalog resides.
The Lightroom catalog has an .lrcat extension.
You will need to copy the catalog file to your new computer.
I highly recommend that you keep your catalog file on your fastest drive, preferably on a solid state drive (SSD).
Step 4: Copy Configuration, Settings, and Presets
Lightroom combines all the settings, configuration files and presets under the Lightroom Settings directory.
The directory contains a massive amount of information related to your Lightroom Catalog. It stores all the develop presets, import and export presets, metadata presets, keyword sets and so forth. If you do not import all the configuration information to your new installation, it can take weeks or even months to recreate it. Importing the directory is an essential step of the migrating process.
Depending on your preferences, the Lightroom Settings directory can be located in the catalog directory or in the Lightroom installation folder.
In my case, I use one catalog organization and prefer to store all my configuration files and presets next to my catalog file. This helps me localize all catalog related data in a single location, but it also means that the settings and presets cannot be shared across multiple catalogs.
You must copy the entire Lightroom Settings folder to a new computer and place them in a new catalog folder or a new Lightroom installation directory.
Step 5: Re-link the New Catalog with the Photo Library
When you have completed the four previous steps, you are ready to launch your imported Lightroom Catalog on a new computer.
The chance that the file structure on your new machine is identical to your old one is very slim. This means that Lightroom won’t be able to find your photos because they are stored in a different location.
When you see a question mark next to a folder inside the Lightroom Library module, this means that it has no idea where to find them and that you need to re-link the missing folders to point them to a new image location.
The good news is that you do not have to do this for every folder. All you have to do is right click at the top of the parent folder and point to the new location where you placed the photo library in Step 2. Lightroom will do the rest by mapping all the folders to their new locations.
Step 6: Migrate Previews (Optional)
I know that many photographers copy their original preview files to a new computer, but I never do.
In Lightroom Preferences, you can specify how long you want to keep full-size previews before they are discarded. Because of the limited disk space on my primary SSD drive, I use the 30-day option. This means that if I do not use a particular image for longer than 30 days, Lightroom discards its preview. But, I find that Lightroom does not manage this option very well. Over a period of months, the preview folder size grows out of control and I have to manually delete the previews to recover valuable disk space.
The migration process gives me an opportunity to start the preview generation process from scratch without importing any unnecessary files.
When I am finished with the migration, I can begin recreating preview files as I need them by using the manual method in Library Module.
TIP: Combine Steps 3, 4 and 5 into one
action SinceLightroom stores the Catalog, Settings andPreviews inside the catalog folder, it makes sense to combine steps 3, 4 and 5 into a single move by copying the entire catalog folder with all its content to a new computer.
Step 7: Move Catalog Backups (Optional)
Lightroom has a built-in functionality to back up the catalog files in case the master catalog is corrupt. This is a very critical functionality because the catalog files contain years of accumulated information. If you lose it, it will be a disaster.
In my case, the backup process is set to a weekly schedule. However, you can configure it to a different frequency.
By default, Lightroom stores catalog backup files inside the Catalog folder.
But, it is highly recommended that you use a different location from your master drive where the catalog resides. The logic here is that if your master drive fails, you will have a backup that is intact on another drive.
While it is recommended that you import backup files to a new installation, it is not critical.
In the 12 years that I have used Lightroom, I have never had any issues with catalog files so I am not very paranoid in this regard.
When I complete the migration process and everything looks good, I create the first backup on a new computer and this is more than enough for me. Plus, I always have a few versions of the catalog backup saved on my Backblaze cloud.
Moving the Lightroom Catalog to a new location is a serious undertaking and can be a disastrous experience if done wrong. But, if you follow the outlined steps, the process will be painless and can be completed in no time at all!
