Alan Baker has already replied, but here's a few more notes.

1.  If you are going to use Migration Assistant, do so during the
    initial set-up when you first turn on the new Mac. Don't do
    it aftwards with separate Migration Assistant app because
    that way can cause some extra issues with things like
    User ID clashes.

2.  Old 32-bit apps will no longer work at all. You will need to
    use some form of virtualisation / emulation to run those if
    needed ... BUT neither Parallels Desktop nor WMWare Fusion
    work on the M1 Macs yet (not sure about other the other
    freeware options).

3.  Some Intel Mac 64-bit apps will also not work - one of which
    being Parallels Desktop. Many apps are still in the process
    of being re-done for M1 Macs (Microsoft has launched an M1
    version of Office, but not yet a universal binary version for
    running on both Intel and M1).

4.  Old Intel Mac apps will take a bit longer to open the first
    time on the M1 Mac as Rosetta translates them (can be 20 secs
    or more for big apps). After that they should open up the
    same or slightly quicker than before. The translation process
    also means the apps wil take up more space on the drive - so
    steer well clear of the 128GB Macs if you use a lot of apps.
