What are the steps involved in upgrading a VSS database from 6.0d to 8.0?
I have a number of VSS6.0d databases (the code goes back around 6 years or
so), and while the latest version of all the files is what I want, it would
be nice not to lose the history of changes.

I have made backups (of course), but I don't think that just pointing to the
old database is right, because my scheduled analyze runs give me the same
error someone else (Bryan Donaldson) has previously (9-May) reported:

Running advanced reference verification.
The file S\DATA\\ is not a valid SourceSafe physical database file. It must
be renamed to a file with an extension or moved to another directory outside
the database.

Validating references.

Some errors were found: run ANALYZE -F to fix these problems.

I'm guessing that there's something like DDUPD that I need to run to upgrade
it, but I'd appreciate any pointers before I go and trample all over it.

Thanks in advance
