No need for 'step-by-step' really )

Antar: just add list.php from any previous release (located in root) if you really need to keep redirects from 'list' to 'page'. Imho if you've used Siena long enough, search engines should have memorized that all 'list.php?c=cat' links have permanently moved to 'page.php?c=cat'.
