Introduction

This page will guide you through the process of migrating from a Kiuwan on premises single-container installation carried out with the deprecated installation tool docker-for-kiuwan.

Migration process

Step 1: upgrade your single-container installation

First of all, you will need to upgrade your current installation to the latest available. A complete upgrade (both Kiuwan and clients) will be needed.

Please follow the steps shown in Kiuwan On-Premises Installation Guide in order to upgrade.

Once the upgrade is completed, you should see this versions in the KOP system administration console:

 
 

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:

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)

Follow the steps provided in Kiuwan On-Premises Installation Guide to prepare your Kiuwan on premise new installation but do NOT perform the installation step (that may be executing install.sh or other scripts depending on your installation needs).

We recommend using a new host(s) machine(s), so the old installation does not interfere in any way.

If it is mandatory for you to use the same machine to install the new Kiuwan on premise, please make sure no persistent volume paths collide.

Step 5: restore your data

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


Step 6: start Kiuwan infrastructure


Step 7: tweak the installation to allow upgrades


Step 8: complete the migration process
