Post-Upgrade Activities ----------------------- 1. Check .htaccess settings (some php settings could become required) 2. If you're using the built-in addressbook, run indexing script: ./bin/indexcontacts.sh. 3. When upgrading from version older than 0.6-beta you should make sure your folder settings contain a namespace prefix if necessary. For example Courier users should add "INBOX." prefix to folder names in main configuration file. 4. Check system requirements in INSTALL file. 5. Update your database and configurations by running: ./bin/update.sh SQLite database upgrade ----------------------- Versions older than 0.9 were supporting SQLite v2 only. Newer versions require database in v3 format. The best what you can do is to convert database file to the new format using command line tools: sqlite OLD.DB .dump | sqlite3 NEW.DB
