    • whUser: root
    • whPasswd: encrypted_password
    • whPort: 3306
    • whDb: platform_analytics_wh
  • mysql-connector-java.jar is present in PlatformAnalytics\lib directory.
  • Disk space sufficient to hold a backup of your MySQL platform_analytics_wh database.

    pgWarehouseDbConnection:

    • pgWhHost: 127.0.0.1

    • pgWhUser: postgres

    • pgWhPasswd: encrypted password

    • pgWhPort: 5432

Migration Workflow

Backup

  1. Provide the path to the directory where the MySQL backup will be stored.

  2. The tool will then begin backing up the MySQL platform_analytics_wh specified in your PAConsumerConfig.yaml file, placing the backup in your specified path.

Restore

  1. Provide the path to the directory where the MySQL backup is stored.

  2. The tool will prompt you again if you are sure you are okay to drop your PostgreSQL platform_analytics_wh schema.

  3. If yes is selected, the platform_analytics_wh schema will be dropped and recreated matching the version of your MySQL dump.

  4. The backup data is then imported into the newly created platform_analytics_wh schema.

  5. The platform_analytics_wh schema will then be upgraded to the latest version of Platform Analytics.

Recommended Upgrade Procedures

  1. On your new MicroStrategy ONE machine, populate the PAConsumerConfig.yaml has the MySQL and PostgreSQL information shown in the prerequisites above.

  2. Copy the mysql-connector-java.jar from your previous installation to the Platform Analytics\lib directory on the new machine.
  3. Go to your Platform Analytics bin directory and call the platform-analytics-data-migration-tool.bat file.
  4. Select the Backup and Restore option (3).
  5. Enter the full desired directory path for the database to be backed up to and restored from.
  6. Wait until the backup is complete. The tool you will then prompt if it is okay to recreate the PostgreSQL warehouse and select yes.
  7. The program will then restore your MySQL backup files into your new PostgreSQL warehouse and the data migration will be complete.
