yes - look at the implementation of the current archives.
You'll see that at the very begining, there is
"archive version number".  This is distinct from
the "class version" described for serializable classes.

This archive version number can be used to just
abort the process, or adjust it's behavior in
accordance with the difference between
the version which made the archive and
the current code version.
