# How to Upgrade to 1Password 3

If you are upgrading from a previous version of 1Password like 2.x, there are a few things you need to do to make sure the process goes smoothly.

## Ensure you are using the new data format

To use 1Password 3, you must have first migrated your data to the new data format, known as the Agile Keychain, introduced in an earlier version of 1Password 2. If you are uncertain whether you are using the Agile Keychain, please keep reading.

Open 1Password > Preferences > Keychain, and look at the button at the very bottom. If it says “Switch Back to OS X Keychain”, then you are using the new data format and can proceed with the upgrade. If, however, the button says “Switch to Agile Keychain”, then you need to migrate your data before proceeding.

This data migration needs to happen before you install 1Password 3.

## Download and install 1Password 3

Installing 1Password 3 is pretty straightforward.

1. Download the latest version of 1Password from our main downloads page by clicking the “Download Now” button.
2. Quit 1Password 2 and all web browsers.
3. Your browser should have automatically downloaded 1Password to your Downloads folder. Locate it, and just drag it into your Applications folder. Replacing the older version will not harm your data, which is stored separately.
4. Double-click the 1Password application to begin the installation. It will walk you through a brief setup, then integrate 1Password with your browsers.
5. Enjoy a more secure and convenient online experience with 1Password!

Note: If you attempt to drag and drop the new version over the older one while 1Password or a browser is still running, you will get an error in Finder. If this happens to you, simply quit all your browsers and 1Password and then try again.

## Upgrade your 1Password 2 license

Customers who purchased 1Password 2 on or after March 1, 2009 get a free license upgrade to 1Password 3 (in fact, those licenses should “just work” in the new version!). All other owners of versions 1 or 2 are entitled to a discounted upgrade price for a 1Password 3 compatible license. Here’s how to upgrade it.
