At this stage, I would leave things as is and prepare for the next spawning (assume you want to hatch some of the eggs and raise them). Several things are at play here.
First, any moving of the eggs and parents will certainly result in their eating the eggs. Once they are guarding a clutch of eggs, the parents should not be "spooked" in any way. They may manage to save some, or not, but if not, they will inevitably spawn again. [I am assuming you have a male/female pair; it is common for females without a male present to lay eggs but they will be infertile obviously.]
Second point is that angelfish generally eat the first few spawns themselves, regardless. This occurs with commercially-raised angelfish but not wild caught angelfish. So unless you acquired wild caught fish from an importer, it may take a few go's before things work out.
Angelfish can be very protective parents (once they have settled down as described above) but any fish in the tank will recognize eggs and make every attempt to eat them. During the night is when they are most vulnerable, as the angels sleep/rest being diurnal fish, but nocturnally-active fish like most catfish including cories will easily get the eggs, or the fry later if they did manage to hatch. So for the future, you might want to set up a spawning tank for the pair.
