Update talend Studio to latest version

[Dhanoop]

Hi team

I am current using Talend Cloud Data Integration platform with version 8.0.1 R2023-11.
I need to update to latest Talend version without impacting the existing jobs.

Please let me how this can be done and what all pre requisites are to be done to update to latest version without impacting the existing jobs.
Also, is there any update required for Talend Remote Engine and TMC once the Talend Studio is updated to latest version.

Thanks in advance

Hello,

As your existing projects are stored on a remote Git repository, you just need to link it to the new version of Talend Studio to retrieve the projects you have previously created. It doesn't affect your existing jobs.

I'm supposing that you've checked this online documentations about:
upgrading-the-talend-projects-in-talend-studio| Qlik Talend Help 

and
upgrading-talend-cloud | Qlik Talend Help 

Here is an official  community article about

Qlik Community: Qlik Talend Studio: How to add features or update Talend Studio Manually in Offline ... 

Hope it helps for you.

Hello,
Please also note that:

• Java 17 is mandatory to run Studio 2024-05 and onwards. (How to setup Java 17)
• Talend Remote Engine has to be upgraded to 2.12.7 or above which is available to be downloaded now. 

For more information, please refer to documentation

Hi @Xiaodi_Shi 

I am opening Talend Studio connecting to Remote GIT repo and all the jobs are live in production. I am using the java 11 version.

While opening the studio, under Local update settings I am providing the Update URL as : Update URL: https://update.talend.com/Studio/8/updates/R2023-11

Once I update the Talend Studio to latest version and Java version to 17, will it cause any impact to any of my jobs in Studio as well as in GIT repo or any issue while running those jobs in TMC as well.

Hello,

You need to make some changes in both talend studio and TMC to make sure Java compatibility level.

In Talend Studio, Data integration Jobs and Routes are compiled with Java 17. Big Data Jobs are compiled with Java 8, but with parameters that make them Java 17 compliant. You can change this compliance level to Java 8 for Routines used in Big Data Jobs.

In TMC, when Java 17 is used to compile, you can specify a different Java version. This feature allows you to use a newer engine version to run the artifacts designed with older Java versions, without the need to rebuild these artifacts, such as the Big Data Jobs, which reply on Java 8 only.

Hi @Xiaodi_Shi 

We are just using Talend Cloud Data Integration Platform and the artifacts we are publishing to TMC and the jobs are ran from there.

Once I update to latest Studio version and using Java 17 version as well, if I publish any job from Studio to TMC, it will be running in TMC ryt without any issues?

I need to make sure no impact will be there even if I update to latest version as multiple critical jobs are running in TMC.

Hello,

Please make sure that your Talend management console tasks are running under the same Java version as what it was published.
It does mean the task was published from Talend Studio using Java 17. The project properties within Talend Studio is currently set to Java 17 compatibility mode, and the Remote Engine is also utilizing Java 17.
You could raise a suport case for your project migration requirement through support cycle with priority so that we could give you a remote assistance on it.
