You'll just have to do exactly as before, but install the advanced mod rewrite version 0.2.0 instead of the 0.0.2.
The phpBB mod rewrite rewriterules have changed a bit, but the principle is still to keep all the old able2know links properly handled in the end of the .htaccess and to let the zero dupe do it's job.
So a good thing, to make sure the switch in url will be as fast as possible is to perform some test on a test server.
So that you lake sure the code is working and update your site in just one attempt
