To migrate from 32-bit to 64-bit on the same platform, you need to make backups of your databases and configurations, then migrate and install the 64-bit software, and then restore your databases and configurations.

Important:

For this procedure, it is assumed that your CAS installation uses a remote database. If you are using a local database, see Migrating 32-bit CAS to 64-bit CAS (Same Platform, Local Database).

Make Backups

These steps are not just to make safety copies. You will need most of these backups to restore your data and configurations after migration. The SQL database backup is not absolutely necessary when you use a remote database, but it is still a very good idea to make a backup of your important data before you start making major system changes.

  1. Make a backup of the current CAS database.

    For more information, see Backing Up MS SQL Server Databases.

  2. Make a backup of the current CSS database.

    For more information, see Backing Up CSS.

  3. Make a backup of the RUM Console database.

  4. Make a backup of the CAS %programfiles%\cas\config\ directory.

    Manually copy this folder and its contents to a safe location.

  5. Make a backup of the CAS %programfiles%\cas\classes\customqueries directory.

    Manually copy this folder and its contents to a safe location.

Migrate and Install the Software

  1. Migrate the operating system from 32-bit to 64-bit (assuming 32-bit DC RUM was installed on a 32-bit OS).

  2. Install the CSS and RUM Console.

Restore the Data and Get the New CAS Installation Running

After the target environment is ready, restore your data and bring the CAS back up.

  1. Restore the CSS database.

    For more information, see Restoring CSS.

  2. Restore the RUM Console database.

    For more information, see Restoring the RUM Console Database.

  3. Install 64-bit CAS.

    It is important that you install exactly the same CAS version (and service packs, if they were present) that you had previously. For more information, see Running a CAS Setup.

  4. Stop and disable the CAS service.

  5. Restore the entire %programfiles%\cas\config\ folder from your backup.

    Manually copy the backup files you made earlier back to the target installation.

  6. Restore the entire %programfiles%\cas\classes\customqueries folder from your backup.

    Manually copy the backup files you made earlier back to the target installation.

  7. Open %programfiles%\cas\config\repository.properties and make sure that the JDBC_URL property is set to the correct hostname/IP of the remote MS SQL server and that it points to the restored database: JDBC_URL=jdbc:jtds:sqlserver://remote_host:1433//CAS;tds=8.0;lastupdatecount=true;.

  8. Make sure the CSS and RUM Console services are running.

  9. Start the CAS service.
