Database Upgrade - MySQL 5.7 to MySQL 8

Commencing late September 2024, Temenos will be undertaking a mandatory program of work to upgrade all Temenos AWS managed Journey Manager databases from MySQL 5.7 to MySQL 8. 

A minor version upgrade of Journey Manager (JM) is required to support MySQL8. This JM upgrade includes security updates arising from recent penetration tests.  

We are confident there will be no impact on clients, however lower environments will be upgraded first giving clients a chance to test before moving to production. 

Who is impacted? 

All AWS Journey Manager customers hosted on a Temenos managed cloud environment will be upgraded to a MySQL8 compatible version of Journey Manager, including production and all lower environments. 

Why are we doing this? 

AWS will end standard support of MySQL 5.7 compatible Amazon Aurora MySQL Editions on 31 October 2024. The recommendation is to upgrade to a MySQL8 compatible edition of Amazon Aurora. 

Benefits of this upgrade 

Upgrading to MySQL 8 will maintain the security, stability and performance of the Journey Manager databases.  

An added benefit of this upgrade is that Journey Manager will be upgraded to the next minor release which contains additional security fixes to keep your environments secure. For example, if you are running JM 2023.10.1 you will be upgraded to the MySQL8 compatible JM version 2023.10.3. 

Upgrade process 

Temenos will use the following phased approach to perform the upgrade: 

Phase 1: Lower environment upgrade 

Temenos support will contact customers to provide more information and schedule the lower environment upgrade. 

Temenos will upgrade all client lower environments (non-production) to the latest minor version of Journey Manager and, in the same outage window, upgrade the Amazon Aurora Edition to version 3 (MySQL 8 compatible). This will be completed outside business hours to minimize client impact. Each client will be notified when this is complete. 

Although Temenos has thoroughly tested the upgrade process, customers are encouraged to perform their own sanity testing on these environments after the upgrade is complete and before the production upgrade. 

Phase 2: Production environment upgrade 

Temenos support will contact customers to provide more information and schedule the production upgrade. 

Given the nature of the update, Journey Manager systems will be offline for this mandatory maintenance. Based on our testing, we estimate that the downtime for this upgrade will be approximately 60-90 minutes.
