Provision question

I am assuming that the version of Provision needs
to be the same as the Progress Database/Client version
that we are using. Such as Provision 8.3 is used for
Progress 8.3. Is this correct? I'm asking because it
looks like our provision software wasn't updated with
our last Vantage/Progress update. Our provision is
8.1 and database/client is 8.3. (We are just starting to look
into using the provision tools, after buying them over a year ago).
If anyone could provide the answer I would appreciate it.
