I have an icosphere.

enter image description here

I need to apply a "Subdivision Surface" modifier to it and then split the edges, but not all the edges, just the edges according to the original mesh.

enter image description here

it is not suitable for me to apply "split edges" before "subdivision surface", then blender also rounds the corners.

enter image description here

I need to transfer information about the "old" edges somehow, but I don't know how to do it.

To achieve the desired result, you would simply have to mark the edges before the subdivision with a boolean value using the Capture Attribute node.

You can then use this captured values after the node Subdivision Surface as a selection for the node Split Edges.
