Bridge CC 2018 does not migrate custom templates from output panel - Watch out!

I just have upgraded to Bridge CC 2018 only to find out that all custom templates I had created in the output module are gone. There does not seem to be an easy solution for this issue as I have been told by Adobe support. The reason for this seems to be that the old output module file format used to store the settings for custom templates where .json files while the new version of Bridge uses .xml files for those. So if you have, like me, many custom templates it might be good if you manually write down all the settings you have used in order to create those templates new in Bridge CC 2018.
