設定 Azure 應用程式以進行進階遷移

請按照下列步驟，在 Azure 入口網站中建立 Microsoft Azure 應用程式。您必須建立應用程式，才能確保資料從 Microsoft Exchange Online 安全遷移至 Google Workspace 帳戶。你可以選擇下列其中一種方式：

使用 PowerShell 指令碼設定自動連線
使用 Azure Active Directory 設定手動連線

使用 PowerShell 指令碼設定自動連線

您必須是全域或具備權限的角色管理員，才能完成這些步驟。

選項 1：使用 Azure Cloud Shell

以管理員身分登入 Azure 入口網站。
按一下 Cloud Shell 「Powershell」。
看到提示時，請建立儲存空間帳戶並接受預設設定。
如要建立應用程式，請輸入下列指令，然後按一下「Enter」：
Install-Module Microsoft.Graph -Scope CurrentUser
如果系統提示您從不受信任的存放區安裝，請輸入 Y，然後按一下「Enter」。

複製下列程式碼區塊，貼到 PowerShell 中，然後按一下「Enter」。

請記下下列憑證並妥善儲存。如果憑證遭到外洩，駭客就可能存取您所有的 Exchange Online 資料。

用戶端密鑰
應用程式 (用戶端) ID
目錄 (租戶) ID

使用 Azure Active Directory 設定手動連線

具體的 Microsoft 步驟可能會因 Azure 入口網站版本和 Microsoft 的更新而異。如需應用程式註冊和授權的最新指引，請參閱 Microsoft 說明文件。

步驟 1：註冊新應用程式

基於安全性考量，建議您將新的應用程式註冊為單一租戶。

以管理員身分登入 Azure 入口網站。
在 Azure Active Directory (Azure AD) 中，前往「App registrations」。
按一下「New Registration」，然後輸入應用程式名稱 (例如「Advanced migration app」)。
在「支援的帳戶類型」中，按一下「僅限這個機構組織目錄中的帳戶」，建立單一租戶應用程式。
按一下「註冊」。

步驟 2：設定 API 權限

選擇下列其中一種做法：

選項 1：手動新增權限

在側邊的「管理」下方，按一下「API 權限」。
依序按一下「Add a permission」「Microsoft APIs」「Microsoft Graph」。
針對「應用程式權限」，請選取：
- calendars.read
- mail.read
- contacts.read
- Directory.read.all
按一下「Grant admin consent for <your organization>」。

選項 2：編輯應用程式資訊清單

開啟應用程式資訊清單。
前往「resourceAccess」: [ ]，然後選擇下列任一選項：
- 如果 “resourceAccess” : [ ] 已有值，請加上半形逗號，然後貼上下列程式碼區塊。
- 如果 “resourceAccess” : [ ] 沒有值，請複製並貼上下列程式碼區塊。
{ "id": "089fe4d0-434a-44c5-8827-41ba8a0b17f5", "type": "Role" },

{ "id": "810c84a8-4a9e-49e6-bf7d-12d183f40d01", "type": "Role" },

{ "id": "7ab1d382-f21e-4acd-a863-ba3e13f7da61", "type": "Role" },

{ "id": "798ee544-9d2d-430c-a058-570e29e34338", "type": "Role" }
按一下「Grant admin consent for <your organization>」。

步驟 3：產生用戶端密鑰

依序點選側邊的「管理」「憑證和密鑰」「新增用戶端密鑰」。
輸入說明，選取到期時間，然後按一下「新增」。
複製用戶端密鑰值並妥善保存。這個值只會顯示一次。

步驟 4：收集應用程式憑證

重要事項：請務必妥善保管應用程式憑證，如果憑證遭到外洩，駭客就可能存取您所有的 Exchange 資料。

按一下「Overview」，並妥善記下下列憑證：

應用程式 (用戶端) ID
目錄 (租戶) ID

Google、Google Workspace 和其他相關符號及標誌均為 Google LLC 的商標。所有其他公司名稱和產品名稱則為相關公司的商標。
