舊系統升級與遷移

分階段升級或遷移舊系統

分階段升級或遷移應用程式,讓每一步都便於管理。我們評估系統依賴、數據和運行成本,與您確定適合業務營運的實施路線。

英文範圍示例

Choose what to keep before replacing the system

Unsupported dependencies, manual exports or fragile connections make ordinary changes difficult. Compare maintenance, refactoring, an API boundary and replacement.

Keep a stable system under a support scope when bounded fixes address the problem. An audit can establish the evidence needed for a migration quote.比較選項

您將獲得甚麼

  • Inventory of retained/replaced components and dependencies.
  • An agreed phased boundary, reconciliation checks and cutover plan.
  • Named acceptance, deployment and rollback decision owners.

需要準備甚麼

  • Source rights, hosting, licences, integration owners and current documentation.
  • Data mappings, preserved business rules and a cleanup owner.
  • Critical dates, operating constraints and accepted rollback conditions.

另行約定

  • Missing access or source rights can prevent a takeover or change the feasible scope.
  • Unbounded feature requests and an ongoing modernization backlog are separate from a component project.
  • Third-party changes, parallel running and observation windows must be agreed.
查看示例

Illustrative sequence: map dependencies → keep existing data ownership → trial an isolated replacement → reconcile agreed records/balances → authorize cutover → decide when to retire the old component.

Acceptance example. The buyer approves mapping and cleanup rules. Trial results meet agreed record/balance checks. The cutover owner can identify when to pause or roll back and who monitors both systems.

Read the sample scope, acceptance and handover records

Do we have to replace everything?

No. Keeping stable components may be the appropriate decision. Scope from the problem, access constraints and dependency evidence rather than a preference for a new stack.

What if the former supplier cannot help?

Record source, account, data and licence ownership first. Missing rights or access are evidence gaps, not promises that can be bypassed.

Can the old and new systems run in parallel?

Assess that option from the data flow and operating constraints. Agree which system accepts writes, how records are reconciled, who monitors exceptions, the observation window and the cutover or rollback decision. Parallel running adds work and infrastructure cost; it is included only when the proposal defines it.

Can we add new features during modernization?

Record new features separately from the behavior being preserved. Assess their effect on mappings, acceptance checks, timing and rollback before approval. A phased proposal can include a defined feature, but modernization is not an unlimited feature backlog.

系統升級服務

明確哪些部分應保留、改進或替換。

程式碼重構與重寫

改進現有程式碼結構,或按需要重寫組件。根據應用程式特點和維護需求,選擇 React、Next.js 或 Go 等技術。

雲端遷移

規劃遷移前,評估託管環境、系統依賴和數據存取權限。批准遷移前,比較實施費用與持續運行成本。

API 整合與中間件

透過約定的 API 將現有系統連接至新工具,明確數據歸屬和錯誤處理方式。

Process

我們的系統升級流程

評估現有系統,分階段遷移,驗證上線結果後再停用舊組件。

01

程式碼審計與可行性評估

我們分析您現有的技術堆疊、系統依賴和業務邏輯。

  • 架構藍圖與風險評估。
02

分階段遷移

逐個替換組件,同時保留您仍需使用的工作流程。事先約定停機時間、回退方案和系統切換責任。

  • 分階段上線計劃。
03

測試與系統切換

批准切換前,檢查關鍵工作流程並核對遷移後的數據。

  • 驗收記錄與系統切換清單。
