R80.10 management server can manage gateways with which versions installed?

R77 and higher is incorrect because it understates the backward compatibility range - R80.10 management supports gateways as old as R76, not just R77 and above.

Check Point's official compatibility matrix for R80.10 specifies that it can manage Security Gateways running R76 and higher - gateways on versions older than R76 fall outside the supported backward compatibility window and cannot be managed by an R80.10 management server.

R75.20 and higher overstates the supported range - R80.10 does not support managing gateways running R75.20, as the minimum supported gateway version is R76.

R75 and higher is incorrect because R80.10 management cannot manage gateways running R75; the minimum supported gateway version begins at R76.
