Need to Change Taxomy terms from one theme to a new theme

I use to have “GameZone” from ThemeFuse and i still have, but because they wouldnt make it Buddypress compatbile because it give some errors in the way it is showing, i try to use codeable to go for this task as ThemeFuse recommended, but after a week no one answered, or give me a offer.

I therefor look for some new theme, which have the Buddypress/BBpress compatible and also have a few extra function i actually miss in the old one.

The new theme from Ghostpool.com is awesome made called Gauge.

There is just one problem i have a clone site of my livesite on the Gamezone theme, installed the new theme, but here is the problem.

I have some taxomies in the old theme there are “Disapering” when i change to new theme. But if i change back to old theme again they appear, but becase the way diffrent the themes are acting with post association, i have only one way to make things go smooth.

1. Do a “Copy/Paste” from Gamezone on EACH game i have ( 150 now ), and retype everything ( and then MANUALLY add all associate post to those games again ) all ready here is the first problem.

2. I try to do another other way around, it was to make a clean install of WordPress , install only Gauge theme, and then import each thing step by step.

I have there for made single export for Post, Games, Reviews etc as they are called.

Post are imported as they should be
Reviews is the first problem because it say “Game Type is invalid term” or something and my guess it is because that term isnt part of the new theme.

Is it some way to add that “Term” in database ?

I have tried numerous of Change Taxomony Plugins to see if i could change post like that, but its like it cant read terms from Theme there isnt active, that means i cant even make a “Move”.

I can show you 2 example how but look each, maybe you know a plugin or someway to change it so it “Fits”

First is the Original way a “REview” is exported

Im thinking if there was a plugin or something there could make this change automatic, but also problem is as i say it “Dissapear on theme if i change, everything i do on theme theme isnt show up on old theme and the other way around.
