Yes the real answer is the poster need QB 2006 UK version first then upgrade existing version to QB 2006.From there its better to upgrade to QB 2012 first thew to latest version.
However if you are registered for vat then I would seriously recommend not doing this.
It would be quicker and easier to install latest version Qb 2016 and then take the TB from old version and import by manual journal entry all the opening balances.
QB old versions can be upgraded to new versions and should be but vat legislation has changed considerably since the version quoted by the poster, it is now much easier to start a new version.
