The only way I can see to do this is to simply build your latest mdb version
in 2003, and then move that application into access 2007, and then start a
new project in VSS.
I really don't think it much wise to attempt any other pathway then the
above. You really don't want to start playing around with the source safe
files and attempt to move them between different versions as I don't believe
anyone has any idea as to how well this would work.
You want to take a known working mdb file, and have 2007 convert that mdb to
an accDB. Any issues of VSS should be eliminated during this conversion
process.
Once the application is running in 2007, then at that point I would start a
new source project.
