Issues migratting instances between differents versions of the same process definition

Hi everyone, i’m facing a problem. I’m having an issue with three duplicate webhook events on the same version of the same process definition; which makes them not work.

Specifically, I was thinking about migrating the instances to a single version and removing the definitions with errors; However, when I do it from Operate an error appears that there are unmapped elements, but it is because they do not appear in the Operate mapping menu (they are signal events - catch). On the other hand, I understand that there is also a migration API but I also cannot find how I could efficiently do the mapping between the elements of one version of an element and another.

Can anyone help me or have any ideas to make this much more efficient? Thanks
