It's not the version but the Feature set you need to change. You need either

1) Advanced Security

2) Advanced IP Services

3) Advanced Enterprise Services

Feature Navigator is the tool to use for this because you also need to check that if you upgrade to any of the above feature sets you still have all the features you are currently using -
