transfer office 2008 between iMac's
I just got an iMac 2019 13", and I transfer my files from my older iMac 13" and the Office 2008 edition didn't transfer over. I have tried to update in my apps but nothing happens, except the option to buy Microsoft Office 365. When I go to that, it shows that it s already purchased (near the download button). When I try to open it up, it says I need to 'Get started with Microsoft 365' I then can't restore my previous purchase.
Any thoughts?
