Stuck with updating to v.2

I am trying to update to version 2. I have installed WPEasyUpdates plugin. I have all the relevant license keys input and accepted. I have clicked to upgrade and have the attached (scary) screen saying don’t proceed without updating.

I use advanced search, custom posts and location manager (but can’t see how I would update them.

I don’t use the other two listed add ons on the screen shot (Review Ratings and Lists – I think I deleted them but they are maybe somewhere still in my system so show up even though they can’t be found).

Anyhow I need to update but am to scared to update without updating the add ons that I use (advanced search, custom posts and location manager) but HOW DO I UPDATE THESE?

Also if I can update these add ons what do I then just proceed with the over all update?

Thanks in advance
