Ikea Besta - compatible old and new?

Hello everyone!

There has been a new Besta system for some time now. Are the new and old parts compatible with each other?
For example, my flaps and drawers in my old Besta cabinets are not equipped with dampers. Can I retrofit something like that now? Thanks!

Best regards, Andre

The new drawers are not compatible with the old fronts. The old Inreda full extensions are of better quality. Maybe some can still be found on eBay, etc.
