Migrating to the new rules schema

Version:

Only available versions of this content are shown in the dropdown

Use the migrate script to migrate the rules tables and other required database objects from the existing rules schema to the new rules schema. To minimize the time required, run the migration scripts from the same data center as the database server.

Pega strongly recommends that you use the Pega-provided migration script. The use of vendor tools to manage this step is not recommended, since there are additional manual steps required to migrate the schema, not documented here, if you do not use the migrate script.
  1. Use a text editor to edit the migrateSystem.properties file in the scripts directory of your distribution image:

    Pega-image\scripts\migrateSystem.properties
  2. Configure the source properties.

    # Connection Information
    pega.source.jdbc.driver.jar=full path/DRIVER.jar
    pega.source.jdbc.driver.class=database driver class
    pega.source.database.type=database vendor type
    pega.source.jdbc.url=URL of database
    pega.source.jdbc.username=Deployment user name
    pega.source.jdbc.password=password
    pega.source.rules.schema=existing rules schema
    pega.source.data.schema=existing data schema     
  3. Configure the target properties.

    pega.target.jdbc.driver.jar=full path/DRIVER.JAR
    pega.target.jdbc.driver.class=database driver class
    pega.target.database.type=database vendor type
    pega.target.jdbc.url=database URL
    pega.target.jdbc.username=Deployment user name
    pega.target.jdbc.password=password
    pega.target.rules.schema=new rules schema
    pega.target.data.schema=temporary data schema
  4. Configure the bulkmover directory.

    pega.bulkmover.directory=full path to output directory
  5. Configure a temporary directory:

    pega.migrate.temp.directory=full path to temporary directory
  6. Configure the operations to be performed by the utility as shown below:

    pega.clone.generate.xml=true
    pega.clone.create.ddl=true
    pega.clone.apply.ddl=true
    pega.bulkmover.unload.db=true
    pega.bulkmover.load.db=true
    pega.rules.objects.generate=false
    pega.rule.objects.apply=false
  7. Save the properties file.

  8. Open a command prompt, and navigate to the scripts directory.

  9. Type migrate.bat (for Windows) or ./migrate.sh (for Linux) to run the script.

Pega Platform writes command-line output to a file in the Pega-image\scripts\logs directory.
