One more investigation for you ... one cannot upgrade from 2.6.x to 3.6.highest if that's you meant by "I will be updating my Moodle version". Moodle 2.6.x upgrades to 3.6.x must be done in stages and marched through versions along the path.
In addition, higher versions of Moodle are leaning towards character set and collation for db not normally available to customers on shared hosting.
Am not trying to discourage you from trying ... just warning it might be a lonely bumpy ride (if on shared hosting). Almost the same on VPS's with 'quickinstall' and 'quick upgrade'.
