Derby Database Schema Upgrade for Tigase 5.1

The schema upgrade is very simple and safe but make sure the current database schema is in version 4.0.

First things first - make a database backup:

tar -czf derbyDB.tar.gz /path/to/derbyDB

If you need to restore database for any reason simply extract files from the backup archive:

rm -rf /path/to/derbyDB
tar -xf derbyDB.tar.gz

Now we can run schema upgrade script

java -Dij.protocol=jdbc:derby: -Dij.database="/path/to/derbyDB" \
		-Dderby.system.home=`pwd` \
		-cp libs/derby.jar:libs/derbytools.jar:jars/tigase-server.jar \ database/postgresql-schema-upgrade-to-5-1.sql
