Actually it looks like a simple VecCopy() works in this situation.
It checks the local sizes of the two vectors, and decides they are still
the same, so is happy to do the copy.

hi
I have a Vec created on a distributed DMPlex (using
DMCreateGlobalVector() or DMCreateLocalVector()).
I then add FV boundary condition cells to the DMPlex, using
DMPlexConstructGhostCells().
I can then create a new Vec on the new DM. What is the best way to
copy the values from the old Vec to the new one?
Regards, Adrian
