A nice seque from the GATOR thread.
Out of the box GATOR is your best bet, but it won't copy hardedge cluster
information, and might slip up on a few UVs here or there - especially if
the object has UV islands. If that isn't good enough you can script it
using the GATOR SDK, but is a lot of work as there are many scenarios to
account for.
The other scripting option is to write something similar to the old
Softimage|3D CopyGeometry+ custom effect which replaces an object in a
hierarchy with another while preserving all relations such as
group/layer/partition assignment, expressions, etc.
I have experience doing both. The Gator path is more robust as it solves
your current problem and becomes a weapon for future work, but you'll need
to be pretty adept at the math to do it well as the GetClosestLocations()
method and related aren't perfect and require some knowledge of the
algorithms to correct the problems. The CopyGeometry+ approach is much
easier to code, but inconsistencies in the SDK will make you want to pull
your hair out as you must do significant testing to make sure you found all
the edge cases where it doesn't work as expected/documented.
That said, if you only have one or two objects, fastest route is to do it by
hand. Scripting will only pay off if this is an ongoing thing.

Subject: Copying geometry from one object to another

Hi,
I have a mesh that has received some fixes and new uv's and I need to take
geo/uvs/hardedges and copy that to an existing object replacing it's
existing geometry/uvs/etc. allowing me to keep the object level stuff
untouched (partitions, animation expressions, etc.)
Using [apply delete i get rid fo the old geo first, letting it just be
replaced by clone] and then clone polygon mesh as well as copy edge data
from source. However the UV's transferred using "copy texture projection
from source" seem to not want to follow along properly. In the texture
editor every point is at 0,0
When showing values before the set data node in the top level of the copy
tx proj compound shows the data correctly, but it doesn't seem to get
applied.
Another curious thing is that after copying the EdgeIsHard property all
edges act as hard when subdividing.

if there is an easier way/script/plugin to do this I'm all ears.
Thank you,
Fabian
