BTW, you'll want to tweak some things between the two .conf files, especially if the 8.1.3 server has more memory. Faster drive array means you probably want to tweak random_page_cost down. Also, 8.1.3 has a lot of new config settings compared to 7.4.x; it'd probably be best to take the default 8.1 config and tweak it, rather than bringing the 7.4 config over. -- Jim C.
