When running upgrade fatal error

I'm trying to run the upgrade for izap,this is the error

Fatal error: Call to undefined function datalist_get() in /home/content/81/4870981/html/patriot/mod/izap_videos/upgrade.php on line 32

I checked and the upgrade is for upgrading from 3.55,that's the error,but I'm trying to upgrade from 1.6.-25

Everything works in izap except the pagination from the "all videos" page,so maybe I need coding done instead of running the upgrade.php

Any body familiar with this problem?
