Upgrading to 2.5.0

What all do I have to do to upgrade to 2.5.0 from 2.3.2? Other than upload the files?

As mentioned in the upgrade instructions,

1. Turn off your wiki. (Ideally you should be disabling the product itself).
2. Upload the files.
3. Run the upgrade script.
4. Turn on your wiki.
5. Check your Wiki URL Manager and deal with any conflicts.
6. Upgrade your addons, if any.

I see categories has an update too, should this be done before or after the vault Wiki upgrade?

Also I am going to buy a 3rd full Wiki for yet to be decided on site name, I have an extra vbulletin license i am not using... but I have an interesting idea.

I will give it a shot on my Lamp forum

Addons should be updated afterward.
