Assuming that your still have - and that you have not erased - your old iPad, you can reset the new iPad and restart the transfer process.
On the new iPad, complete the setup as a new device with the same AppleID. After setup completes, reset the iPad:
Settings > General > Transfer or Reset iPad > Erase All Content & Settings
After the iPad restarts, you can perform the transfer process again…
These support pages should get you started with setup of your new iPad - and the methods of transferring your data from old to new iPad:
Set up your iPhone, iPad or iPod touch – Apple Support
Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support
Use Quick Start to transfer data to a new iPhone, iPad or iPod touch – Apple Support
If the donor iPad, from which you are transferring your data precedes iOS12.4, QuickStart will not be available.
“Transfer” is rather a misnomer. In reality, your data and setup is merely cloned to the new device. Nothing is moved or removed from the original device.
An alternative is to restore either an iCloud or iTunes backup to the new device:
