General information

Read all of the instructions on this page carefully before proceeding with the upgrade process.
Run a pre-production test first.
  • Update is only required if Jahia has been updated from Jahia 7 to Jahia 8
  • jExperience 1.12 is compatible with jCustomer 1.5.1 and only with Jahia 8.0.0.0+
  • jCustomer 1.5.1 relies on Elasticsearch 7.4.2. This change of Elasticsearch version, from 5.7.3 to 7.4.2 is the reason why Unomi data needs to be migrated. 
  • While jExperience module is stopped or jCustomer not available, no events are tracked and no personnalised or optimised (A/B test) content is displayed to users.

Update path:

Update Jahia 7 to Jahia 8 but don't start Jahia until jCustomer is migrated. 

Follow instructions from https://academy.jahia.com/cms/render/default/customer-center/jahia/how-to-upgrade/7.3.4.1-8.0.0.0 but do not start jahia until jCustomer is migrated. 

Migrate jCustomer from 1.4.1 to 1.5.1

To migrate from jCustomer 1.4.1 to 1.5.1 , please follow the procedure described in Unomi documentation. 

Any mention of "Unomi 1.4.0" can be interpreted as jCustomer 1.4.1

https://unomi.apache.org/manual/latest/index.html#_data_model_changes_for_apache_unomi_1_5_0 

Start Jahia

As jExperience 1.11.0 is not compatible with Jahia 8, it won't be started.

Install jExperience 1.12.0 module and start it.

Get jExperience from the store or from [provide link to jExperience] 

[Provide link to jahia store and screenshot of the store page]

Install the module.

Start the module.

You have to update and start jExperience to 1.12 AFTER jCustomer being migrated to 1.5.1. 

Enjoy jExperience 1.12.0 on Jahia8!
