如果您准备出售旧 iPad，则应确保在出售之前擦除设备上的所有个人数据。本指南将在您出售或赠送旧 iPad 之前擦除旧 iPad 上的所有内容，从而使您顺利过渡到新 iPad。
1. 准备好出售你的旧(Old)iPad 了吗？立即
备份(Back)
此清单适用于所有 iPad 型号，例如 iPad mini、iPad Air或 iPad Pro。您应该首先备份所有重要数据。您可以考虑使用 iCloud 进行在线备份，或使用Finder或 iTunes 进行本地备份。
请注意，Apple仅在其服务器上存储 iCloud 备份 180 天。因此，如果您计划在备份旧 iPad 六个月后更换新 iPad，您可能会丢失 iCloud 上的所有数据。这就是为什么在您的计算机上进行本地备份更适合那些不打算立即切换到新 iPad 的人。
首先，让我们了解如何使用 iPadOS 上的内置备份功能将
您的Apple设备备份到 iCloud。(Apple)
首先，解锁您的 iPad 并将其连接到 Wi-Fi 网络。然后，前往设置 > [您的姓名] > iCloud > iCloud备份(Backup)，然后点击立即备份(Back Up)。这将开始对您的 iPad 进行完整备份。
该过程完成后，您将在“立即备份”(Back Up)按钮下方看到一条消息，告诉您上次备份已在不久前完成。
如果您不想使用 iCloud，请使用Mac或Windows PC 对 iPad 进行完整备份。如果您有Mac ，请使用USB数据线将 iPad 连接到您的Mac。接下来(Next)，在Mac上打开Finder ，您将在边栏中的(Finder)Locations部分看到您的 iPad 。在Finder(Finder)边栏中选择 iPad 的名称。
iTunes 备份是使用旧Mac或 Windows PC 的任何人的最佳方法。
使用USB(USB)数据线将您的 iPad 连接到Mac或 PC 。您必须在 iPad 上输入密码，然后点击弹出窗口中的“信任”按钮，询问您是否要信任这台计算机。(Trust)然后，在计算机上打开 iTunes，然后单击“音乐(Music)”下拉菜单和“图书馆(Library)”按钮之间的 iPad 图标。
在这个阶段，您可以在Finder(Finder)中打开“常规(General)”选项卡，或者如果您使用的是 iTunes，请单击侧栏中的“摘要”选项卡。(Summary)然后，在备份(Backups)下，选择将 iPad 上的所有数据备份(Back)到此计算机。
如果您希望添加额外的安全层，您也可以使用密码保护备份，但请务必使用密码管理器(use a password manager)或同样可靠的工具来保存此密码。如果您忘记了 iPad 备份密码，您将无法访问数据或使用它来恢复到新 iPad。
要添加密码，请选中加密(Encrypt)此备份并键入您要使用的密码。当您准备好备份时，单击立即备份(Back Up)。您的 iPad 现在将备份到您的Mac或 PC。
2. 退出 iCloud、App Store和 iMessage
下一步需要您退出 iCloud 和其他Apple服务。这将确保您旧设备的新所有者可以成功登录他们的Apple ID并毫无问题地使用 iPad。iOS 15 和 iPadOS 15 具有防盗功能(iOS 15 and iPadOS 15 have an anti-theft feature)，如果之前的所有者没有删除它
，则不允许人们登录和使用Apple设备。(Apple)
首先，您应该检查是否需要继续使用 iMessage。此服务适用于所有Apple设备，包括您的 iPhone、iPad 和Mac。如果您打算使用任何其他Apple设备，则无需注销 iMessage，但如果您不使用任何Apple设备，则应禁用它。
要在 iPad 上执行此操作，请前往Settings > Messages”，然后关闭 iMessage。
接下来，您应该退出 iCloud 和App Store。您可以通过转到设置 > [您的姓名]，然后点击页面底部的红色退出按钮来执行此操作。(Sign Out)您会看到一个弹出窗口，您可以在其中点击右上角的退出(Sign Out)。
Apple将要求您确认是否要注销。再次点击退出(Sign Out)。
3.取消配对蓝牙配件
请务必取消配对 AirPods、游戏控制器、蓝牙(Bluetooth)键盘等配件。打开 iPad 上的“设置”(Settings)应用并转到蓝牙(Bluetooth)以检查哪些配件已配对。点击每个配件旁边的 i 按钮，然后选择忘记(Forget)此设备(Device)。
请记住(Remember)，您无法将Apple Watch与 iPhone 以外的任何设备配对，因此无需担心会从 iPad 取消配对。
4. 抹掉你的 iPad
现在您已在 iPad 上退出 iCloud，您可以抹掉设备上的所有内容(erase all content on the device)。为此，请打开“设置”(Settings)应用程序，前往“General > Transfer或重置(Reset)iPad”，然后轻点“抹掉所有内容(Erase All Content)和设置”(Settings)。您的 iPad 将要求输入密码。输入它，然后点击擦除(Erase)以完全擦除 iPad。这将关闭激活锁并禁用“查找”(disable Find My)。
或者，您可以将 iPad 连接到MacBook或 PC 并在那里擦除它。在Mac上，您会在Finder边栏中看到 iPad。单击(Click)iPad 的名称，然后单击右侧窗格中的恢复(Restore)按钮以擦除 iPad 上的所有内容。
您可以在较旧的Mac(Mac)或Windows上使用 iTunes 执行相同的操作。将 iPad 连接到计算机，打开 iTunes，然后单击窗口上半部分音乐(Music)和资料库之间的 iPad 图标。(Library)现在转到侧边栏中的“摘要(Summary)”选项卡，然后单击右侧的
“恢复iPad”。(Restore)
5.取出SIM卡
将 iPad 恢复为出厂设置后，请不要忘记取出设备中的SIM卡。这仅适用于 iPad 的蜂窝版本，因此如果您使用的是仅Wi-Fi的iPad，则无需担心。
6. 从受信任(Trusted) 设备列表中删除您的 iPad(Devices)
如果您在Apple ID上启用了双重身份验证，您的 iPadOS 或 iOS 设备会收到双重身份验证代码。因此，在出售或赠送您的 iPad 时，您也应该将其从接收这些验证码的受信任设备列表中删除。
您可以通过在任何浏览器中访问Apple 帐户页面并使用您的(Apple account page)Apple ID密码登录来执行此操作。在左侧窗格中选择设备(Devices)，从列表中选择您的旧 iPad，然后单击从帐户中
删除。(Remove)
7.找到所有配件和盒子(Box)
了解了所有基础知识之后，是时候寻找 iPad 随附的配件和随附的包装盒了。这包括USB 数据(USB)线、充电器、耳机和手册。根据您的 iPad 型号，某些配件可能未随设备一起提供。
如果您拥有包装盒和所有配件，您的 iPad 在 eBay 或亚马逊(Amazon)等网站上的转售价值可能会上升。如果设备在保修期内，您应该寻找原始发票以帮助 iPad 的新主人。如果他们有任何保修索赔，它可能会派上用场。纸质发票很有用，电子邮件中的软拷贝也很有用。
8. 以旧换新或出售 iPad
恭喜，您已准备好出售旧 iPad。您可以在亚马逊(Amazon)和 eBay 等网站上搜索您的 iPad 的确切型号名称，以便在列出之前查看转售价值。在列出之前，请确保出售的 iPad 与您的情况相似。
您还应该查看Apple Trade In 网站(Apple Trade In site)，看看您是否可以从Apple获得更好的价格。
9. 将数据传输到您的新 iPad
最后，如果您给自己买了一台新 iPad，您可以通过将数据传输到新设备来从上次中断的地方继续。有三种主要方法可以做到这一点。
如果您同时拥有 iPad 和新设备，请打开新 iPad 并将其靠近旧 iPad（在擦除旧 iPad 之前）。您会在旧 iPad 上看到一个提示，询问您是否要将数据传输到新 iPad。您可以按照屏幕上的提示操作，所有数据都将传输到新设备。
或者，您可以在新 iPad 的设置过程中从 iCloud 或计算机备份中恢复。
9 Things You Should Do Before Selling Your Old iPad
If you’re ready to ѕell your old iPad, you should ensure that you wipе all personal datа from the device before you sell іt. This guide will make your transition to a new iРаd smooth bу erasing all сontent from your old iPad before you sell it or give it awаy.
1. Ready To Sell Your Old iPad? Back Up Now
This checklist is the same for all models of the iPad, such as the iPad mini, iPad Air, or iPad Pro. You should first back up all your essential data. You can consider using iCloud for an online backup or Finder or iTunes for a local backup.
Note that Apple stores iCloud backups on its servers only for 180 days. So, if you’re planning to switch to a new iPad more than six months after backing up the old one, you could lose all your data on iCloud. That’s why a local backup on your computer is better for those who don’t immediately plan to switch to a new iPad.
First, let’s learn how to back up your Apple device to iCloud using a built-in backup feature on iPadOS.
First, unlock your iPad and connect it to a Wi-Fi network. Then, go to Settings > [YOUR NAME] > iCloud > iCloud Backup, and tap Back Up Now. This will begin a full backup of your iPad.
When the process is complete, you’ll see a message below the Back Up Now button telling you that the last backup was completed a short while ago.
If you don’t want to use iCloud, use your Mac or Windows PC to take a full backup of the iPad. If you have a Mac, connect the iPad to your Mac using the USB cable. Next, open Finder on your Mac, and you’ll see your iPad under the Locations section in the sidebar. Select the name of your iPad in the Finder sidebar.
ITunes backup is the best method for anyone using an older Mac or a Windows PC.
Connect your iPad to the Mac or PC using the USB cable. You’ll have to enter the passcode on your iPad and tap the Trust button in the pop-up asking if you want to trust this computer. Then, open iTunes on the computer and click the iPad icon between the Music drop-down menu and the Library button.
At this stage, you can open the General tab in Finder or click the Summary tab in the sidebar if you’re using iTunes. Then, under Backups, select Back up all of the data on your iPad to this computer.
You can also protect the backup with a password if you wish to add an extra layer of security, but be sure to use a password manager or an equally reliable tool to save this password. If you forget the iPad backup password, you won’t be able to access the data or use it to restore to a new iPad.
To add a password, check Encrypt this backup and type the password you wish to use. When you’re ready to back up, click Back Up Now. Your iPad will now be backed up to your Mac or PC.
2. Sign Out of iCloud, App Store, and iMessage
The next step requires you to sign out of iCloud and other Apple services. This will ensure that the new owner of your old device can sign in to their Apple ID successfully and use the iPad without trouble. iOS 15 and iPadOS 15 have an anti-theft feature that doesn’t allow people to sign in and use the Apple device if the previous owner hasn’t erased it.
First, you should check if you need to continue using iMessage. This service works on all Apple devices, including your iPhone, iPad, and Mac. If you plan to use any other Apple device, you don’t need to deregister iMessage, but if you don’t use any Apple device, you should disable it.
To do this on an iPad, go to Settings > Messages, and turn off iMessage.
Next, you should sign out of iCloud and the App Store. You can do this by going to Settings > [YOUR NAME], and tapping the red Sign Out button at the bottom of the page. You’ll see a pop-up where you can tap Sign Out in the top-right.
Apple will ask you to confirm if you want to log out. Tap Sign Out again.
3. Unpair Bluetooth Accessories
Be sure to unpair accessories such as AirPods, gaming controllers, Bluetooth keyboards, etc. Open the Settings app on your iPad and go to Bluetooth to check which accessories are paired. Tap the i button next to each accessory and select Forget This Device.
Remember that you cannot pair your Apple Watch with any device other than the iPhone, so there’s no need to worry about unpairing it from your iPad.
4. Erase Your iPad
Now that you’ve signed out of iCloud on your iPad, you can erase all content on the device. To do this, open the Settings app, go to General > Transfer or Reset iPad, and tap Erase All Content and Settings. Your iPad will ask for the passcode. Enter it, and tap Erase to wipe the iPad entirely. This will turn off the activation lock and disable Find My too.
Alternatively, you can connect your iPad to your MacBook or PC and erase it there too. On a Mac, you’ll see the iPad in the Finder sidebar. Click the name of the iPad and then click the Restore button in the right pane to erase all content on the iPad.
You can do the same thing using iTunes on an older Mac or Windows. Connect your iPad to the computer, open iTunes, and click the iPad icon between Music and Library towards the upper half of the window. Now go to the Summary tab in the sidebar and click Restore iPad on the right.
5. Remove the SIM card
Once your iPad is restored to factory settings, don’t forget to remove the SIM card in the device. This applies only to the cellular version of the iPad, so if you’re using a Wi-Fi only iPad, there is nothing to worry about.
6. Remove Your iPad From the List of Trusted Devices
If you’ve enabled two-factor authentication on your Apple ID, your iPadOS or iOS device receives two-factor authentication codes. So, when selling or giving away your iPad, you should remove it from the list of trusted devices that receive these authentication codes too.
You can do this by going to the Apple account page in any browser and signing in with your Apple ID password. Select Devices in the left pane, select your old iPad from the list, and then click Remove from account.
7. Find All Accessories and the Box
With all the basics covered, it’s time to hunt for the accessories shipped with the iPad and the box it came in. This includes the USB cable, charger, earphones, and manuals. Depending on the model of your iPad, some accessories may not have come with the device.
If you have the box and all accessories, the resale value of your iPad may go up on sites such as eBay or Amazon. In case the device is under warranty, you should look for the original invoice to help out the new owner of the iPad. It may come in handy if they have any warranty claims. The paper invoice is useful, and so is a soft copy that arrives in your email.
8. Trade In Your iPad or Sell It
Congratulations, you’re ready to sell your old iPad. You can search sites such as Amazon and eBay for the exact model name of your iPad to see the resale value before you list it. Ensure that the iPads on sale are in a similar condition as yours before you list it.
You should also check the Apple Trade In site to check if you can get a better price from Apple.
9. Transfer Data to Your New iPad
Finally, if you bought yourself a new iPad, you can pick up where you left off by transferring your data to the new device. There are three main ways to do this.
If you have both your iPad and the new device with you, switch on the new iPad and bring it close to your old iPad (before erasing the old one). You’ll see a prompt on the old iPad asking if you want to transfer data to the new one. You can follow the on-screen prompts, and all data will be transferred to the new device.
Alternatively, you can restore from an iCloud or a computer backup during the setup process for the new iPad.
