Step 2: stop Kiuwan

To stop the running Kiuwan and prevent creating more data before backuping it up, run this commands in the Kiuwan on premise host. Make sure there are no running analysis before stopping the application server:

Code Block
docker exec -it [kiuwan_on_premise_container_name] /bin/bash
supervisorctl stop wildfly

Step 3: backup your data

Now that the application server is stopped but not the container itself, you can access the MySQL server and persistent volume to backup your data.

Using mysqldump or MySQL Workbench, backup these schemas data and structure:

  • opt_activity
  • opt_cinc
  • opt_insight
  • opt_metamodel
  • opt_qmm
  • opt_transaction

Access your persisten volume and backup central and source code repositories, located in:

  • $DIR_PERSISTENT_VOLUME/$KIUWAN_HOST/KiuwanCentralWorkingDirectory
  • $DIR_PERSISTENT_VOLUME/$KIUWAN_HOST/repos/kiuwanSourceCodeRepository

Step 4: install Kiuwan on premises using the new installer tool (kiuwan-cluster)

Step 5: restore your data

To restore your data into the new persistent volumes and database, follow these steps:
