You need to add it to Time Machine. Choose Select Disk or Add or Remove Backup Disk.

Physically detach the old drive and give TM no choice in the matter but to use the new drive. If that fails do a restart and again retry with only the new drive attached.
TM can use multiple drives. I've used as many as three so each drive will benefit from a unique name: TimeMachine 1, Time Machine 2 and etc. Or whatever you choose to ID them uniquely
Many modern external drives come formatted for Windows. Using Disk Utility, erase the new drive and format it with an Apple format.
I want to make the new external drive the destination for time machine. After I unmount old drive and replace it with the new one, time machine won't back up. It wants to use the old one
