Nav2009 to Nav2013

I am attempting to convert a customers database from Nav2009 to Nav2013.

2 Questions... The customer is running 4.03 object with Nav2009 executables. Is that gonna fly or do I need to full upgrade to 2009?

I am looking for an upgrade toolkit 601800. My nav2013 disk only has 601700.. Any ideas?

Thanks in advance...
