Hi Robert,
That feature has been gone for a long time for security reasons. If you have been using it with a transpose number of 1, it is a huge risk.
We have a thread from 2008 announcing this:

Since version 3, the upgrade script displays a prominent warning about this feature being removed, so you have the option of preparing for it before continuing with the upgrade. If you upgraded from v2.x to 3.x, that message would have been displayed at the start of the upgrade process.
