Depending on how many remote loads you have, you may still be able to use a non-HomeWorks system like RadioRA 2. Caseta might be an option if you want to limit the control to 75 zones. It's also severely limited in 3-way/4-way circuits.
Grafik Eyes and the 150 switches will work as stand-alone controls. You don't need to replace them unless you want them on the new control system. Grafik Eyes may be an issue because they can have 6-zones in a 4-gang box.
