17+1. 进入应用首页，点击"使用want.param迁移简单数据"按钮，进入want.param迁移页面。
18+2. 在输入框中输入需要迁移的数据。
19+3. 对端设备，点击系统Dock栏，触发应用接续，数据接续到对端设备。
20+ 
21+### 使用分布式对象迁移基础数据
22+ 
23+1. 进入应用首页，点击"使用分布式对象迁移基础数据"按钮，进入分布式对象迁移页面。
24+2. 在"基础数据"区域输入文字数据和数字数据。
25+3. 在"数据对象"区域输入分布式对象的文字数据和数字数据。
26+4. 对端设备，点击系统Dock栏，触发应用接续，数据接续到对端设备。
27+ 
28+### 使用分布式对象进行单个文件资产迁移
29+ 
30+1. 进入应用首页，点击"使用分布式对象单文件迁移"按钮，进入单文件迁移页面。
31+2. 在"基础数据"区域输入文字数据和数字数据。
32+3. 点击"添加优质首图"区域，弹出菜单选择从本地设备获取图片。
33+4. 选择图片后，图片显示在页面中。
34+5. 对端设备，点击系统Dock栏，触发应用接续，数据和图片数据接续到对端设备。
35+ 
36+### 使用分布式对象进行多个文件资产迁移
37+ 
38+1. 进入应用首页，点击"使用分布式对象多文件迁移"按钮，进入多文件迁移页面。
39+2. 在"基础数据"区域输入文字数据和数字数据。
40+3. 点击"添加图片"区域，弹出菜单选择从本地设备获取图片（最多支持9张）。
41+4. 选择图片后，图片列表横向显示在页面中。
42+5. 对端设备，点击系统Dock栏，触发应用接续，数据和图片数据接续到对端设备。
