I live in a Victorian house and am replacing a 2 gang light switch that contains two modules (i.e. each module is a two-way switch) that has a fair amount of complex wiring. One of the old modules has 4 holes to put wires in (including the live switch wire) and the other module has 3 holes to clamp the wires in.
The replacement 2 gang switch has a much more simplified wiring configuration using L1, L2, and COM and I am uncertain as to how to know which set of wires from the old switch go where in the new switch (see below). I do know that the combined earth wires connect to the back of the mounted box.
So my question is, can someone help me with getting the right wires in the right holes? Many thanks in advance!

You have the wrong replacement switch
Your existing switch isn't a 2-way/2-way two-gang assembly like you thought it was, it's actually a 2-way/intermediate (North American translation: 3-way/4-way) two-gang assembly. So, you'll need to get the correct switch before you go any further with this.
