Does "All the data still" mean, that the fields are not re-ordered? A lot of the solutions change the order of the fields.
Currently, Matlab has the function renameStructField.
When I run the test suite on my computer, this solution works. It passes the test suite.
This fails, if the fieldname to be replaced appears as part of another fieldname. Example: S.ab=1; S.a=2; renamefield(S, 'a', 'c')
