org.h2.dev.util.Migrate

public class Migrate
extends Object

Migrate a H2 database version 1.1.x (page store not enabled) to 1.2.x (page store format). This will download the H2 jar file version 1.2.127 from maven.org if it doesn't exist, execute the Script tool (using Runtime.exec) to create a backup.sql script, rename the old database file to *.backup, created a new database (using the H2 jar file in the class path) using the Script tool, and then delete the backup.sql file. Most utility methods are copied from h2/src/tools/org/h2/build/BuildBase.java.
