Hello,

I think it is inevitable that some SAS programs need changes when migrating
to a new SAS version.
What we did was document all problems we found and suggest to the users how
to 'fix' it.
This gives the users some help in converting their sasv6 programs to v8.
Furthermore, we gave the user the possibility to do a testrun in the new
version, so they could see the impact.
