Your new iPad appears to have a USB-C port - not Lightning. The new iPad will have been supplied with a USB-C to USB-C charging/data cable - and a USB-C Power Adapter.
If your PC/Mac computer only has the older USB Type-A connections, you simply require a USB Type-A to USB-C cable. These are readily available from good computer stores - and from Apple. Here is one example of suitable cable manufactured by mophie, marketed by Apple:

As for transferring your data from old to new iPad, you don’t necessarily need to use your computer. These support pages should get you started with setup of your new iPad - and outline the available 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:
