why 2.3.0 to upgrade to 3.0 ?
 

I am just wondering why the vB staff are saying that people can only upgrade to vB3 from 2.3.0 since an earlier version that I have did not seem to have any problems database structure wise - I ran the db script for vB3 compatibility and no errors came up.
What do you guys think?

Actually ... I think you can go from 2.2.9 to 3.0 ... but it could be other minor tweeks in the actual data itself ...

If you're putting it off because you've never upgraded before, then don't worry about it ... I was in the same boat the other day when I went from 2.2.6 to 2.3.0 to 3.0.0b3 ... the updating process from 2.2.6 to 2.3.0 was extremely short and simple !!! :)

Anyhow ... obviously I'm no expert and someone can give you a better answer ... lol .. I just wanted to let you know that you can upgrade from 2.2.9 if that's what you're running !!! :)

Your database has to match the proper schema to upgrade. 2.2.9 and above changed the schema.

If you have an old version you can run the upgrade scripts and skip upgrading the files since the vB3 upgrade script doesn't care about them.
