How can I upgrade or migrate my Retropie Micro SD card data from a Raspberry 3 A+ to a Raspberry 4 B?

I just bought a Raspberry 4 Model B 2GB RAM and basically I just want to move my SD card with Retropie buster 4.6 from my Raspberry 3 Model A+ to the new one. Is there any way to do it?
What version of RetroPie do you have currently installed ? If you used an image version older than 4.6, then you'll need to install from a new 4.6 image on the new system.
To transfer your existing files, backup your ROM/BIOS/Config files from the 3A+ installation, then restore them on the new installation.
