Upgrading Kiuwan On-Premises (full)

Step 1: keep your old kiuwan-cluster installer

Step 2: download kiuwan-cluster latest version

Step 3: check if you need to follow specific steps for your Kiuwan On-Premises version

 

Specific upgrade notes

This section provides information that you may need to follow in case you are upgrading one of these specific versions (see Checking for updates section if you want to check which version is installed in your company):

...

If you have currently installed Kiuwan On-Premises version 2.8.1910.1, you will need to follow this guide in order to adapt your Kiuwan On-Premises infrastructure to the latest version.

Due to changes in how Redis Cluster is created through the installation process, in order to keep your installation up to date with the latest infrastructure, you will need to follow a different approach to perform a full upgrade from this version.

You will need both the kiuwan-cluster version you used to install 2.8.1910.1 and the latest available kiuwan-cluster (that can be downloaded here https://static.kiuwan.com/download/onpremise/kiuwan-cluster.tar.gz). We will refer to this locations:

  • [INSTALL_DIR_OLD]: where the old kiuwan-cluster version was untared.
  • [INSTALL_DIR]: where the new kiuwan-cluster version has been untared.

Step 1: stop kiuwan services

*stop-kiuwan.sh (version vieja)

Step 2: update your current configuration

*update.sh (version nueva)

Step 3: prune current containers

*uninstal.sh (version nueva)

Step 4: clean Redis cluster data

*Borrar los datos del redis antiguo (data-local/Redis/data/**).

Step 5: update Redis cluster node information

*Cambiar en el fichero globalConfig.properties las direcciones de los nodos de redis.

redis.cache.nodes=172.17.0.1:6379,172.17.0.1:6380,172.17.0.1:6381,172.17.0.1:6382,172.17.0.1:6383,172.17.0.1:6384

redis.store.nodes=172.17.0.1:6379,172.17.0.1:6380,172.17.0.1:6381,172.17.0.1:6382,172.17.0.1:6383,172.17.0.1:6384
