Upgrade If you choose this option, UltraLite upgrades the database file to the native format of the current version of the software. This upgrade makes it impossible to use the database from older versions of UltraLite, including applications developed with older versions of the software.
Open Read Only If you choose this option, UltraLite opens the database in read-only mode. Any changes you make are discarded when UltraLite Interactive SQL closes, even if you commit your changes.
