So you are certain there are no changes to the structures
being serialized between the two versions?  For example if your
1.47 was 32-bit and your 1.70 is 64-bit, I wonder if that makes a
difference.

Perhaps you should dump out the raw bytes of a structure
serialized by 1.47 and then the raw bytes of the same structure
serialized by 1.70 and then figure out the difference between the
two, and that may lead you to an answer.

Perhaps you could change the serialization format to something
else temporarily for this test, like the xml serializer, so you can
better understand what the difference is, or if the problem is
limited to the binary serialization format.  Then you will be closer
to the root cause of the issue.
