利用 VM Import/Expor 地端快照部署在AWS雲端伺服器上（工作日常）

您需確認匯入的映像和磁碟快照是否符合格式，請見以下官方文檔。

[+] Importing a VM as an image using VM Import/Export - Export your VM from its virtualization environment - https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-image-import.html#export-vm-image

[+] Importing a disk as a snapshot using VM Import/Export - Prerequisites - https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-import-snapshot.html#import-snapshot-prerequisites

您可以透過 VM Import/Export 來匯入您地端的 VM 映像或磁碟快照，並以此建立 EC2 實例。

[+] What is VM Import/Export? - https://docs.aws.amazon.com/vm-import/latest/userguide/what-is-vmimport.html

整體流程為以下：

上傳 VM 映像 或 磁碟快照至 S3。

[+] Importing a disk as a snapshot using VM Import/Export - Prerequisites - https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-import-snapshot.html#import-snapshot-prerequisites

指定此 S3 檔案並匯入 AWS。

以 VM 映像建立 EC2 實例 或 映像快照建立 EBS 卷。

然而，較為建議使用 MGN 來進行搬遷。MGN 是一種高度自動化的搬遷解決方案，可簡化、加快將應用程序遷移到 AWS 的成本並提供較多的功能性，且並沒有 VM Import/Export 因其“匯入”性質所導致的格式限制。

整體流程如以下：

建立 Replication Servers 來進行搬遷工作。

[+] Replication Settings - https://docs.aws.amazon.com/mgn/latest/ug/replication-settings-template.html

添加來源伺服器，即安裝 Replication agent 至您的地端伺服器。

啟動設置，包含 Test 與 Cutover。
