Problems while migrating sas codes and datasets from 9.1 to 9.3

[LRN]

Hi

Do I have to change any functions or any type of codes used in 9.1 while migrating to 9.3? Because my friend said she had faced some problems with some of the functions and she had to rewrite the programs.

Thanks

Depends on what's in your code, look at the migration documentation, but you'll also need to test your code because you're going up 2 levels at once.
