Our database migration code should be able to handle upgrading the  
database from that far back, so you can just skip straight to 1.18.
The only problem with database migration might be the 1.5 to 1.6 iirc  
where some collations in the database schema were changed.
It's been ages since then so it's possible that our code for that change  
has rotted a bit.

If you do have any issue with going straight to 1.18, instead of going one  
version at a time you can just do one upgrade to something like 1.11 and  
then jump all the way to 1.18 from there. No need to do every version  
upgrade incrementally.
