# Migrate Data before Upgrading

All your 1Password data is stored in a file called a keychain. You must migrate this data file to a new format before you can use 1Password 3. If you install 1Password 3 before migrating your data, you will receive this message because your 1Password data is still stored in the Mac OS X keychain:

Because 1Password 3 uses the new data format to support its new features, it is not compatible with the previous format, the Mac OS X keychain. Please note that all other applications will continue to use the Mac OS X Keychain; only the 1Password data will be migrated to the new data format.
