Upgrading Your Database
A database is only guaranteed to be accessible by the same minor release of TimesTen that was used to create the database. When you upgrade the TimesTen software and you would like to use the new release to access a database that was previously created, create a database with the new release. Then use the ttMigrate
utility to copy the tables, indexes, and table data from the old database to the new one.
See Upgrades in TimesTen Classic in the Oracle TimesTen In-Memory Database Installation, Migration, and Upgrade Guide for details.
