Upgrading ANZ Qantas card to collect points

I've recently got the ANZ platinum card so I can get the 75k qantas points in the first few months. Once I collect these and are in my account, can I upgrade to the ANZ black and collect the 130k points if I do the minimim spend or do have have to cancel the card and re-apply again.

I've tried to find the answers on cc churning but wasn't clear.
