1、下载好最新的胖瘦AP的系统（V2R3C200）
我用的是AP6010DN
胖系统：FatAP6X10XN_V200R005C10SPC700.bin
瘦系统：FitAP6X10XN_V200R003C00SPC200.bin
2、AP要采用本地供电，并与升级电脑直连
因电脑和AP要直连，所以不支持POE，要本地供电。
目前限制如此，以后可能会有改进。
3、转换是命令行操作，用console线连
目前转换只支持在AP上进行，只支持命令行升级，不支持在AC上操作，不支持批量转换
电脑要用Console线和AP的Console接口相连，ap网口与pc段连接，用超级终端操作
4、电脑上要安装FTP或TFTP软件，手工定义地址
FTP软件是3CD，升级全程tFTP不能关掉
电脑地址169.254.1.200，ap默认地址：169.254.1.1
5、因为AP默认是瘦AP，故先示例是瘦转胖
二、瘦AP转胖AP

三、胖AP转瘦AP
升级前要修改地址
因AP初始后IP是169.254.1.1和FTP不在同一网段，所以要修改地址，记得保存
