Well, it depends on the type and model of your current equipment e.g.

Single Boosters Hybrid Floor and Wall (BF4-P, BF8-P, BW7-P):  These units are all upgradeable. Just by purchasing the Hybrid 7 Multicontroller (contact info@nilfiskfood.com for item number)

Mainstations Hybrid – P (MU421 and MU 422): These units are all upgradable. However, due to complexity this is not recommendable.

Hybrid Foamatic Mainstation and Satellite:  It will be possible to upgrade to Hybrid 7 later this year. Just by downloading the new Hybrid 7 software.

Multi Boosters (BF16, BF24, BF32, BF40, BF48-P)can also be upgraded to Hybrid 7 but we would not recommend it, because of the complexity.
