If you have the same topology, even the vertex indexes, it is relatively easy: [![enter image description here][1]][1] You can use *transfer attribute* in *Index* mode: [![enter image description here][2]][2] The problem may occur if you have the same topology, but the indices are messed up. In this case you can try to use *Transfer the vertex order* add-on: https://bartoszstyperek.gumroad.com/l/copy_verts_ids If two meshes have different vertices positions use editmode Copy vert ID from sidebar: [![enter image description here][3]][3] First you need to select two, adjacent faces on source mesh - copy mesh id's, and then, select two similar faces on target mesh and paste IDs. Operation has to be repeated for each island (disconnected mesh parts) separately. [1]: https://i.sstatic.net/Yi1OF.gif [2]: https://i.sstatic.net/Il7jH.png [3]: https://i.sstatic.net/Rb6aG.png
