When upgrading K-Meleon you can bring all of your old settings over. If you upgrade between minor releases (like 76.X.1 to 76.X.2), you can transfer your entire profile folder to bring over bookmarks, passwords, and settings. If you upgrade between major releases, it's better to transfer individual files between profiles.

Backup your old K-Meleon profile

First, you need to back up your existing profile:

1. Open a file manager.
2. Navigate to K-Meleon\Profiles\<your.profile>\
3. Copy the entire profile folder to another area of your computer like the desktop.
4. Keep this back up around until you've tested out your updates.

Transfer an Entire Profile

To transfer the entire profile:

1. Install the new version of K-Meleon, but don't run K-Meleon yet.
2. Navigate to your new installation's profiles folder at K-Meleon\Profiles\ and it should be empty. (K-Meleon won't look for or create a default profile until it starts up.) If you see a default profile in this folder, delete it.
3. Copy and paste the entire profile folder from your old K-Meleon installation.
4. Start K-Meleon and it should automatically find and use your old profile with all of the correct settings and bookmarks.

Transfer individual files

When upgrading between major releases, it's recommended to transfer individual files between your old profile and new profile:

1. Install the new version of K-Meleon, and start K-Meleon.
2. Navigate to your new installation's profiles folder at K-Meleon\Profiles\ and you should see a default profile created by K-Meleon. This folder will be empty until you start K-Meleon for the first time.
3. Open your new profile and your existing profile in separate filer manager windows.
4. Copy and paste any settings below that you want to transfer.
5. Re-start K-Meleon.
