如要開始使用 Google Cloud Migration Center，您必須在 Google Cloud中建立機構和專案，並啟用 Migration Center。
本文將說明建立專案的各種選項，以及如何啟用 Migration Center。
事前準備
如要使用 Google Cloud 控制台，您必須擁有 Google 帳戶。如要瞭解如何建立新的 Google 帳戶，或如何使用現有的電子郵件地址建立新的 Google 帳戶，請參閱「建立 Google 帳戶」。
選擇正確的路徑建立專案
如果您是第一次使用 Google Cloud，請建立 Google Cloud 帳戶，並利用免費試用和 Google Cloud 免費方案產品，開始使用 Google Cloud。您可以使用 Migration Center 執行預估費用，並免費建立評估。
如果您與 Google Cloud 合作夥伴合作，並想進行評估，但沒有 Google Cloud 機構，則有下列選項：
使用合作夥伴的機構。您可以請 Google Cloud 合作夥伴 Google Cloud 為您建立專案。
申請企業版試用方案。您可以請 Google Cloud 合作夥伴為您取得 Enterprise Trial。企業試用方案會為您提供 Google Cloud 機構和專案，無須註冊，也不需要與帳戶建立付款卡關聯，還會提供額外抵免額，讓您開始使用其他 Google Cloud 產品。
如果您已在 Google Cloud上建立機構，即可立即開始使用 Migration Center，且不需額外付費。您可以建立新專案，直接在 Migration Center 中執行費用估算和評估作業。您也可以利用已連結的 StratoZone 帳戶執行其他評估作業，不必額外付費。如果您需要協助，且機構政策允許，可以將Google Cloud 客戶工程師新增至專案，讓他們處理評估作業。
最後，如果您已在 Google Cloud上建立機構，但因機構政策而無法新增 Google Cloud 客戶工程師，請申請 Enterprise Trial。
下圖可協助您決定最適合的路徑。
啟用移轉中心
首次從 Google Cloud 控制台的 Google Cloud 專案存取 Google Cloud Migration Center 時，您必須啟用 Migration Center。不過，如果您想快速產生離線費用估算值，可以直接前往「估算費用」頁面，無須啟用 Migration Center。詳情請參閱「開始進行費用預估」。

To use the Google Cloud console, you need a Google Account. To learn how to create a new Google Account, or to learn how to use an existing email address to create a new Google Account, see [Create a Google Account](https://support.google.com/accounts/answer/27441).\n\nChoose the right path to create a project\n-----------------------------------------\n\nIf you're new to Google Cloud, create a Google Cloud account and take\nadvantage of the\n[Free Trial and Google Cloud Free Tier products](/free)\nto get started with Google Cloud.\nYou can use Migration Center to run a cost estimate and to create\nan assessment at no cost.\n\nIf you're working with a Google Cloud partner and want to perform an\nassessment, but don't have a Google Cloud organization,\nyou have the following options:\n\n- **Use your partner's organization**. You can ask your Google Cloud partner to create a project for you in their Google Cloud organization.\n- **Request an Enterprise Trial**. You can ask your Google Cloud partner to obtain an Enterprise Trial for you. An Enterprise Trial provides you with a Google Cloud organization and project with no sign-up required, no payment card associated with the account, and with additional credits to start using other Google Cloud products.\n\n| **Note:** Google Cloud customer engineers have administrator access to the Enterprise Trial organization. To use an Enterprise Trial, you need to accept the terms and conditions.\n\nIf you already have an organization on Google Cloud, you can start using\nMigration Center immediately at no extra cost.\nYou can create a new project to perform a cost estimation and run an assessment\ndirectly in Migration Center. You can also take advantage of a\nconnected [StratoZone account](/migrate/stratozone/docs/about-stratozone)\nto perform additional assessments at no extra cost.\nIf you need help and your organization policies allow, you can add your\nGoogle Cloud customer engineer to the project and let them handle\nthe assessment.\n\nFinally, if you already have an organization on Google Cloud, but cannot\nadd your Google Cloud customer engineer due to your organization policies,\nrequest an Enterprise Trial.\n\nThe following diagram can help you decide the right path for you.\n\nActivate Migration Center\n-------------------------\n\nThe first time you access Google Cloud Migration Center from a Google Cloud project\nin the Google Cloud console, you need to activate Migration Center.\nHowever, if you want to generate a rapid, offline cost estimate, you can do\nthis directly from the **Estimate cost** page without activating\nMigration Center. For more information, see\n[Start a cost estimation](/migration-center/docs/estimate/start-estimation).\n\n#### Permissions required for this task\n\nReview the\n[permissions required to activate Migration Center](/migration-center/docs/roles-and-permissions#activate).\n\nTo activate Migration Center, follow these steps:\n\n1. In the Google Cloud console, go to the Migration Center page.\n\n [Go to Migration Center](https://console.cloud.google.com/migration?gtm_source=documentation>m_source_id=activate_migration_center_migration_center)\n2. If prompted, to enable the required APIs for Migration Center, click\n **Enable APIs**.\n\n3. From the **Region** list, select the region where you want\n Migration Center to store and process the information about\n your migrations.\n For the full list of available regions, see\n [Migration Center locations](/migration-center/docs/locations).\n\n | **Note:** The region you select cannot be changed later.\n4. If you already have an Expert Request number provided by Google,\n enter it in the **Expert Request number**\n field, without the `ER-` prefix, then click **Next** .\n If you don't have an Expert Request number, click **Skip**.\n\n5. To accept the default migration preferences, click **Next**. You can\n edit or add migration preferences later.\n\n6. To confirm your activation, click **Continue**.\n\nGrant access to Google customer engineers\n-----------------------------------------\n\nIf you want to let Google Cloud customer engineers access your\nMigration Center project to help you with your migration,\nyou must first give your consent by accepting the\n[terms and conditions](/terms/migration-center).\nDo the following:\n\n1. In the Google Cloud console, go to the Migration Center page.\n\n [Go to Migration Center](https://console.cloud.google.com/migration?gtm_source=documentation>m_source_id=ce_consent)\n2. Click settings **Configure\n Migration Center**.\n\n3. Click **Approve Google Cloud customer engineer access**. A dialog opens\n with the terms and conditions.\n\n4. Read the terms and conditions, then click **Accept**.\n\nAfter you accept the terms and conditions agreement, you must give the\nappropriate permissions to your Google Cloud customer engineer.\nFor more information, see the\n[list of permissions to give](/migration-center/docs/roles-and-permissions#manage).\n\nUpdate your Expert Request number\n---------------------------------\n\nTo update your Expert Request number after activating Migration Center,\nfollow these steps:\n\n1. In the Google Cloud console, go to the Migration Center page.\n\n [Go to Migration Center](https://console.cloud.google.com/migration?gtm_source=documentation>m_source_id=activate_migration_center_migration_center)\n2. Click settings **Configure\n Migration Center**.\n\n3. Select **I have an Expert Request number**.\n\n4. In the field that appears, enter your Expert Request number, without\n the `ER-` prefix.\n\n5. Click **Save**.\n\n(Optional) Enable a service perimeter\n-------------------------------------\n\nWith VPC Service Controls, you can configure service perimeters around the\nMigration Center resources and control the movement of data\nacross the perimeter boundary.\n\nTo learn how to enable a service perimeter, see\n[Secure your data with a service perimeter](/migration-center/docs/service-perimeter).\n\nAdd users to your project\n-------------------------\n\nTo let other users access your Google Cloud project, for example if you\nwant a Google customer engineer to help you with your assessment, grant them\nthe [permissions required to manage resources](/migration-center/docs/roles-and-permissions#manage_resources)\nin Migration Center.\n\nAdditional users must create their own Google Account before you can\nadd them to your project. If you encounter issues, see how to\n[troubleshoot common login problems](/migration-center/docs/troubleshooting/troubleshoot-login).\n\nWhat's next\n-----------\n\n- Learn how to [estimate your Google Cloud costs](/migration-center/docs/generate-estimate).\n- Learn how to [start an asset discovery](/migration-center/docs/start-asset-discovery)."]]
