Update H2 Database from 1.3.175 to 2.X
Not following these steps will result in data loss!
These steps are only required when a H2 database is used. No Migration is required when other databases are configured.
1. Download Driver for Migration:
2. Identify Path to *.h2.db file
<webapp>/<kgsPRoduct>/work/<product>/store/<product>.h2.db3. Stop application Server ( make sure that *.lock.db files aren't in the folder anymore)
4. Backup H2 Files by copy all files in the folder to a new directory
5. Execute export Script
java -cp h2-1.4.199.jar org.h2.tools.Script -url "jdbc:h2:file:<PathToDBFile>;MODE=MySQL;AUTO_SERVER=true;cipher=AES" -user "kgs" -password "<password>" -script export.sqlDo not use a file extension in <PathToDBFile>. Example: ./webapp/migration/work/store/KGSMigration
6. Check the export File, it should not be empty and contains values from the tables
7. Download H2 Driver for migration target (>=2.1.214):
http://www.h2database.com/html/download.html (Binary.jar)
8. Delete the V1 Database (<Product>.h2.db, don’t forget the backup!)
9. Create V2 File
java -cp h2-2.1.214.jar org.h2.tools.RunScript -url "jdbc:h2:file:<PathToDBFile>;MODE=MySQL;AUTO_SERVER=true;cipher=AES" -user "kgs" -password "<password>" -script export.sql -options FROM_1X10. Start Application server and check database entries
11. Delete both H2 Driver and export.sql file.
