Modernisasi Sistem Lama
Modernisasi & Migrasi Sistem Lama
Pindahkan aplikasi yang ada ke lingkungan penerapan yang disepakati. Tinjau hak akses kode dan data, ketergantungan, fitur, serta biaya saat ini. Bandingkan biaya migrasi, operasional, pemeliharaan, dan waktu pengembalian investasi tanpa mengasumsikan penghematan otomatis.
Contoh lingkup dalam bahasa Inggris
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.Bandingkan pilihan
Hasil yang Anda terima
- Inventory of retained/replaced components and dependencies.
- An agreed phased boundary, reconciliation checks and cutover plan.
- Named acceptance, deployment and rollback decision owners.
Yang perlu disiapkan
- 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.
Disepakati terpisah
- 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.
Lihat contoh
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 recordsDo 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.
Keahlian Modernisasi
Jalur peningkatan sistem lama yang komprehensif
Refaktor aplikasi sistem lama monolitik ke kerangka kerja modern seperti React, Next.js, dan Go.
Nilai lingkungan hosting saat ini, biaya, ketergantungan, dan kebutuhan data sebelum memilih penerapan baru. Migrasi tidak otomatis menghemat biaya.
Hubungkan sistem lama dengan alat baru melalui API yang didukung. Pastikan akses, arah data, penanganan kesalahan, dan batasan penyedia sebelum implementasi.
Pendekatan Modernisasi Kami
Tentukan fungsi yang dipertahankan, urutan migrasi, rekonsiliasi data, dan rencana pemulihan sebelum berpindah.
Audit Kode & Kelayakan
Kami menganalisis tumpukan, dependensi, dan logika bisnis Anda saat ini.
- Cetak biru arsitektur dan penilaian risiko.
Migrasi Strangler Fig
Ganti komponen secara bertahap jika batas sistem memungkinkan. Sepakati perpindahan, pemantauan, dan cara kembali ke sistem lama jika pemeriksaan belum terpenuhi.
- Rencana peluncuran bertahap.
Pengujian & Peralihan
Pengujian paralel yang ketat sebelum peralihan akhir.
- Lingkup & Pengiriman
Keterlibatan Fleksibel
Harga transparan untuk migrasi kompleks
Migrasi Lingkup Tetap
Terbaik untuk: Peningkatan komponen tertentu
Untuk modul sistem lama yang terdefinisi dengan baik.
Keunggulan
Kriteria penerimaan dan tanggung jawab peralihan sistem disepakati
- Implementasi rekayasa dalam lingkup pekerjaan yang disepakati
- Arsitektur dan rencana migrasi
- Menyetujui peralihan sistem dan proses pemulihan
Tim Teknik Khusus
Terbaik untuk: Perbaikan sistem lengkap
Pengembangan berkelanjutan ditawarkan setelah spesialis, lingkup, ketersediaan, serta kapasitas aktual dikonfirmasi. Tim yang langsung tersedia tidak dijanjikan.
Keunggulan
Integrasi dan pengiriman berkelanjutan
- Kapasitas spesialis dikonfirmasi sebelum komitmen
- Implementasi dan penerimaan yang disepakati
- Tanggung jawab operasional yang jelas
Dukungan Pasca-Migrasi
Sepakati pemantauan, pembaruan, dan tanggung jawab dukungan untuk sistem yang dimigrasikan.
Pemantauan Kinerja
Pengaturan pengamatan waktu nyata.
Pembaruan Berkelanjutan
Patch kerangka kerja dan keamanan rutin.
