Talend Studio and Remote Engine Update

[Dhanoop]

Hi team

I am currently using Talend Cloud platform V8.0.1 R2023-11. I am planning to update the Talend studio to latest available patch version. Also, I need to update the Talend Remote Engine as well.

Please let me know if there will any issue in existing jobs which are currently running in production environment once I update the talend studio and talend remote engine.

Thanks
DBS

Hello, 

There may be some challenges migrating your jobs from R2023-11 to the latest monthly patch (R2026-01 at this posting); which, in general, may be contributed to changed/removed/migrated components, and updating the compiling code to use Java 17 instead of in 8 compatibility mode.

The best practice would be to clone your existing remote branch to a new one, that is focused strictly on migrating the code, and doesn't impact your existing code (compiled with the R2023-11 patch). 

If your team does encounter specific issues, please open up a support ticket with Qlik. When doing so, along with sharing all the details, please also share the job(s) from the R2023-11 and R2026-01 (or newer) Studio instances for Support to review.

DBS - we're in similar situation - but coming from 2025-04.

Here's what we do - 

On one studio instance - we install the new version of the Studio. We create a testing branch and push it to git.

We then have a testing plan (with a full development environment db) - we test all the pipelines that have known distinct components.

Once each of those components test through OK, we can proceed with the update to the studio environment.  It's tedious, but it's required.

Hi Tim

If possible, could u please provide with the detailed steps you have done for this migration.

The java version, changes to Talend Remote Engine version. And also, once the Talend Remote Engine was updated, were there any issues to the jobs running on Production.

Thanks
