迁移到Shopify：使用商店导入器应用导入 CSV 文件
如果您要从现有 Shopify 商店或 Store Importer 应用支持的平台之一迁移到 Shopify，则可以使用 Store Importer 应用导入产品、客户和库存数据。
在现有导入的顶部导入数据
如果认为您在之前的导入中遗漏了一些内容，则可以通过点击开始新导入在当前导入的顶部再次导入您的商店数据。
如果您的 Shopify 商店或之前的导入中已包含客户，则这些客户将会更新。客户首先进行邮箱匹配，如果找不到邮箱匹配项，则进行电话号码匹配。如果找到匹配项，则会更新现有记录，如下所示：
免税和营销订阅状态将被覆盖。
将添加导入内容中的标签、地址和备注。
如果现有记录中的名字、姓氏或电话号码字段为空，并且已包含在导入的客户记录中，则会添加这些字段。
如果导入包含您 Shopify 商店中已有的产品，则会跳过导入中的匹配产品，而不会将其导入。导入完成后，导入摘要中会显示跳过产品的列表。
删除商店数据导入
如果您对数据导入不满意，则可以将其删除。例如，如果您的数据导入包含许多失败项目，则删除该导入并重试可能会有所帮助。您可以仅删除最新的导入。需要等待数据完全删除才能开始其他导入。
步骤
在导入完成页面上，点击删除导入。
在删除导入对话框中，点击删除导入。
删除所有导入的文件后，点击开始新导入即可开始其他导入。
客户密码的注意事项
由于密码已加密，您无法将客户密码从其他平台迁移到 Shopify。因此，仅会将客户记录迁移到 Shopify，但不会迁移客户账户。
Shopify Plus
如果您使用的是 Shopify Plus 套餐，则可以使用 Bulk Account Inviter 向客户发送一封电子邮件，提示他们重置密码并激活账户。

Importing CSV files with the Store Importer app
If you're migrating to Shopify from an existing Shopify store, or one of the platforms supported by the Store Importer app, then you can use the Store Importer app to import your product, customer, and inventory data.
Import data on top of an existing import
If you think you missed something in your previous import, then you can import your store data again on top of your current import by clicking Start new import.
If your Shopify store or previous import already contains customers, then they are updated. The customers are first matched by email address, and then telephone number if no email address match is found. If a match is found, then the existing record is updated as follows:
Tax exempt and marketing subscription statuses are overwritten.
Tags, addresses, and notes from the import are added.
If the first name, last name, or telephone number fields are empty in the existing record and included in the imported customer record, then they are added.
If an import contains products that are already on your Shopify store, then the matching products in the import are skipped and not imported. A list of the skipped products is shown in the Import summary after the import is complete.
Delete a store data import
If you’re unsatisfied with a data import, then you can delete it. For example, if your data import contains many failed items, then it might be helpful to remove that import and try again. You can delete only your latest import. Wait for the data to delete completely before you start another import.
Steps
On the Import complete page, click Delete import.
On the Delete import dialog, click Delete import.
After all your imported files are deleted, click Start new import to start another import.
Considerations for customer passwords
Because passwords are encrypted, you can't migrate customer passwords from another platform to Shopify. As a result, only customer records are migrated to Shopify instead of customer accounts.
Shopify Plus
If you are on the Shopify Plus plan, then you can use the Bulk Account Inviter to send customers an email message that prompts them to reset their password and activate their accounts.
