Checking for upgradable transformers in uploaded workspaces?

Hi everyone,

 

I was wondering if there’s a smart way to check whether any of the transformers in my uploaded workspaces (on FME Flow) are out of date or could be upgraded.

 

Right now, the only method I know is to download each workspace one by one, open it in FME Form, run the upgrade process, and then re-publish it back to Flow. That feels quite time-consuming when you have many workspaces.

 

Is there a built-in feature, script, or workaround that can help identify which workspaces contain upgradable transformers without having to go through them individually?

 

Thanks in advance for any tips!

    The fmw reader will return all transformers and their current_transformer_version and the max_transformer_version for a workspace.

    Before you do, you may want to consider implications due to possible changes in default behavior, see https://docs.safe.com/fme/html/FME-Form-Documentation/FME-Form/Workbench/Working_With_Transformer_Versions.htm#ShouldYouUpgrade

    Personally, I hardly ever bulk upgrade transformers, and if I do, I do a full test run to compare the results from before and after, so that I’m certain that the behavior hasn’t changed.

    This. I would not advise upgrading transformers without heavy testing. Only specific transformers when you have a problem or know what is going on. And still then test the results.

    Alright! I'm going to have to take a closer look at that. It's really the isolation of which workspaces that have these upgradable transformers that I'm really after. I realise an automatic upgrade might be a bit of a wishful thinking on ny part.
