[support] Upgrade How-To

[Tom Holmes Jr.]

I have one Drupal site hosted at SiteGround.org.   I only have 1 node 
posted and I have done very little with this site so far.
When I ran their Fantastico create script, it installed Drupal 5.1.  
I'm not quite ready to go to Drupal 6 yet since not all the modules I 
want to use have been re-written yet.
So, I want to update from Drupal 5.1 to 5.7 and I know that might 
involved some database changes.

So, how do I update?  I am sure there is a Wiki, or instructions on how 
to do this.
If you can just point me in the right direction, I will attempt an 
update on my own.  
But ... is there anything I should watch out for?

Thanks!
                            Tom
