Opening an UltraLite Java edition database with UltraLite 12.0.1 upgrades the database so that it is no longer compatible with UltraLite 12.0.0.

If you have multiple versions of SQL Anywhere on your computer, you must pay attention to your system path when using UltraLite utilities to make sure that you are using the version 12 utilities. See Utility versions and the upgrade process.

UltraLite's file format changed between versions 9 and 10 and then again between versions 11 and 12. UltraLite version 12 cannot read UltraLite databases created using any prior version of the software.

For version 10 and 11 UltraLite databases, use the version 11 ulunloadold utility to generate an XML file that can then be used by ulload to create a version 12 database. Once the database is upgraded, it cannot connect to version 10 or 11 applications, utilities, and software. See Upgrading databases created with previous versions of UltraLite.

For version 9 and earlier UltraLite databases, use the version 9 ulunloadold utility to generate an XML file that can then be used by ulload to create a version 12 database. Attempting to connect version 9 or earlier databases with UltraLite 12 results in an error on database startup. See Upgrading databases created with previous versions of UltraLite.
