Very new. Recent purchase of Raspberry Pi 4 (4Gb) for my son. It came with a 16Gb SD card with NOOBS and we have installed Raspbian as per the instructions. I have also purchased a new 128Gb SD card and would like to just clone the operating system and all installs of other software (Plex etc) we have done etc across to this card and store the original disk as an emergency backup.
So I have the original card in the Pi and have the new card which I can add using a USB reader and thus will have both attached. Can I just drag one across to the other or do I need to run through a sequence of formatting and then running some scripts etc.
Once done as said want to take out the original card, swap new one into the slot and then this becomes my primary boot and HD.
Thanks in advance.
