了解移轉期間的預備活動Understand staging activities during a migration

如升級模型文章所述,「預備」是資產遷移至雲端的時間點。As described in the article on promotion models, staging is the point at which assets have been migrated to the cloud. 不過,它們尚未準備好升級至生產環境。However, they're not ready to be promoted to production yet. 這通常是移轉的遷移程序最終步驟。This is often the last step in the migrate process of a migration. 在預備過後,工作負載便會由 IT 營運或雲端營運小組管理,以便讓其準備好用於生產環境。After staging, the workload is managed by an IT operations or cloud operations team to prepare it for production usage.

交付項目Deliverables

預備資產可能尚未準備好用於生產環境。Staged assets may not be ready for use in production. 必須先完成數個生產環境整備檢查後,我們才會認為此階段已完成。There are several production readiness checks that should be finalized before this stage is considered complete. 以下是通常與資產預備完成相關聯的交付項目清單。The following is a list of deliverables often associated with completion of asset staging.

  • 自動化測試。Automated testing. 所有可用於驗證工作負載效能的自動化測試都應該先執行,才能結束預備程序。Any automated tests available to validate workload performance should be run before concluding the staging process. 資產離開預備程序後,與原始來源系統的同步處理便會終止。After the asset leaves staging, synchronization with the original source system is terminated. 因此,在資產進入預備狀態以便進行最佳化之後,就更難以重新部署所複寫的資產。As such, it is harder to redeploy the replicated assets, after the assets are staged for optimization.
  • 遷移檔。Migration documentation. 大部分移轉工具都可以針對所要遷移的資產產生自動化報告。Most migration tools can produce an automated report of the assets being migrated. 為了清楚起見,請在結束預備活動之前,記下所有遷移後的資產。Before concluding the staging activity, all migrated assets should be documented for clarity.
  • 設定文件。Configuration documentation. 對資產所進行的任何變更 (在修復、複寫或預備期間) 都應該記載下來以供完成營運整備。Any changes made to an asset (during remediation, replication, or staging) should be documented for operational readiness.
  • 待辦項目文件。Backlog documentation. 請更新移轉待辦項目以反映處於預備狀態的工作負載和資產。The migration backlog should be updated to reflect the workload and assets staged.

下一步Next steps

在測試並記載預備資產後,您便可以繼續進行最佳化活動。After staged assets are tested and documented, you can proceed to optimization activities.
