I took a break from iPhone development this week to finally get around to porting our old blog entries over to the new MVC architecture. The reason why it was a little tricky is because I had to work out how to get the old entries' primary keys to relate to the new entries primary keys. What I ended up doing was sticking the old ones into a column in the new table and then do insert into's to get the comments and categories to link up (I still have to display those relationships on the website).
