    Hi,

    Does kettle support backword compatibility?. we were using kettle 3.2.0 version and we have recently upgraded to kettle 4.3.0 version. can we go back to previous version with 4.3.0 repository?

    Not directly (by firing up PDI 3.2.0 and trying to connect to the 4.3.0 repository). But you may be able to export the 4.3.0 repository and import it into a 3.2.0 repository.
    Why are you downgrading?

    In the event you are asking if you can use the 3.2.0 repository with the 4.3.0 tools, the answer is that you can upgrade the repository. That being such a large jump, I highly recommend backing up your 3.2.0 repository first. If the direct upgrade fails, an export/import will probably work.

    Hi,
    We have cutomers who are using Kettle 3.2 version, if we develop new module in Kettle 4.3.0, can we extract that module from 4.3.0 and give it to 3.2 users? So that they can import and use that module in 3.2 version. Can we do this?

    Thanks

    Okay, that is a little different. Kettle 4.3 has a lot of plugin features that 3.2 does not (repositories, UI perspectives, etc...), however 4.3 still supports the plugin features that 3.2 did.
    So if you are making a Job Entry or Transformation Step and follow the plugin structure of 3.2 it should work for both (or at least require minimal changes to make it work in both). Any other type of plugin and it will probably be less backwards compatible.

    Post Does kettle support backword compatibility

    Hi ,

    As per your comment, there might be little bit changes between Kettle 3.2 and 4.3.0 version. we are trying to explain one scenario whatever we have faced issue when we back from 4.3.0 to 3.2 version.

    There are job setting difference beween 3.2 and 4.3.0 version, whenever we have imported 4.3.0 version job into 3.2 version repository we have missed Schema and Table names in job log setting. because of this reason job is not running in 3.2 version.

    Is there any list of items you have, what steps will not work when we goback from 4.3.0 to 3.2 version ?. how can we acheive this issue ?
