Re-Installing KNIME AP while maintaining prior extensions

With 5.12 LTS insisting that we cannot do an in-place upgrade, in order to move to it a fresh install is needed. I prefer not to overwrite a prior install in case I need to quickly go back to it, so typically I install to a fresh new folder.

However I do like to carry over all of the extensions that I have previously installed from the various software sites.

Is there a way to easily pull from an old install all the extensions that were installed, and apply it to a new install?

Right now I’m opening up workflows, and KNIME is detecting they are missing certain extensions, and I keep having top stop to install them, restarting, etc, which is time consuming. This is of course with all the relevant software sites in place.
