Upgrade 2019 imac to SSD etc.

[Robert Withers]

Hi, Apple says on the phone that I can use the same SSD as for the imac pro and that the apple store will upgrade it for the cost of the 1 TB card. Is this true? It’s a big job to pack up and move this 27″ 2019 imac.

I figure I’ll have to go to a Tb 3 external dock for a different graphics card.

Thanks,

Robert
