Moving project from 4.13 to 4.15 (Post Processing Volumes ?)

I’d like to upgrade my 4.13 project to 4.15 but when I did all my post processing volumes have gone to their default settings in the color correcting section. Some of the setting seem to have been retained but on the tools they’ve updated my settings have been set to default.

Is there a way to keep the legacy post processing volume tools or somehow covert to the newer one automatically?

It would be a large task to fix them all manually.

Thanks for your time!
