<h3id="required-reading">Required Reading</h3>
<p>This is an add-on section for moving the contents of a previous EmuNAND to your new SysNAND CFW, then removing the old EmuNAND partition. Note that the terms EmuNAND and RedNAND refer to slightly different implementations of <ahref="http://3dbrew.org/wiki/NAND_Redirection">the same concept</a>.</p>
<p>Note that if you have any payload files other than <codeclass="language-plaintext highlighter-rouge">GodMode9.firm</code> in the <codeclass="language-plaintext highlighter-rouge">/luma/payloads/</code> folder on your SD card, holding (Start) on boot will display a “chainloader menu” where you will have to use the D-Pad and the (A) button to select “GodMode9” for these instructions.</p>
<pclass="notice--danger">You MUST have already installed Luma3DS and boot9strap to use this.</p>
