Modernisasyon ng Legacy
Pag-upgrade at Paglipat ng Lumang Sistema
Ilipat ang kasalukuyang application sa napagkasunduang deployment. Suriin muna ang pinahihintulutang source at data access, dependencies, features, at kasalukuyang bayarin. Ihambing ang migration cost, operating costs, maintenance, at payback. Hindi garantisado ang pagtitipid.

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.Ihambing ang mga opsyon
Ano ang matatanggap mo
- Inventory of retained/replaced components and dependencies.
- An agreed phased boundary, reconciliation checks and cutover plan.
- Named acceptance, deployment and rollback decision owners.
Ano ang ihahanda
- 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.
Hiwalay na pagkakasunduan
- 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.
Tingnan ang halimbawa
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.
Kadalubhasaan sa Modernisasyon
Mga komprehensibong landas ng pag-upgrade ng legacy
I-refactor ang mga monolitikong legacy application sa mga modernong framework tulad ng React, Next.js, at Go.
Pagkasunduan ang saklaw, teknikal na contact, milestone at pamantayan ng pagtanggap bago magsimula. Kumpirmahin sa proposal ang availability ng espesyalista at petsa ng simula.
Ikonekta nang maayos ang mga lumang sistema sa mga bagong tool gamit ang mga modernong REST o GraphQL API.
Aming Diskarte sa Modernisasyon
Pagkasunduan ang launch check, katanggap-tanggap na downtime at recovery responsibility. Hindi magagarantiya ang external platform approval o walang patid na serbisyo.
Audit ng Code at Feasibility
Sinusuri namin ang inyong kasalukuyang stack, dependencies, at business logic.
- Architecture blueprint at risk assessment.
Unti-unting Paglipat ng mga Bahagi
Pagkasunduan ang launch check, katanggap-tanggap na downtime at recovery responsibility. Hindi magagarantiya ang external platform approval o walang patid na serbisyo.
- Plano ng unti-unting rollout.
Pagsusuri at Paglipat sa Bagong Sistema
Masusing parallel testing bago ang final switch.
- Saklaw at Delivery
Flexible na Pakikipagtulungan
Transparent na pagpepresyo para sa mga kumplikadong migration
Migration na May Tiyak na Saklaw
Pinakamahusay para sa: Pag-upgrade ng partikular na bahagi
Para sa mga legacy module na malinaw ang saklaw.
Ang Kalamangan
Napagkasunduan ang pamantayan sa pagtanggap at mga responsibilidad sa paglipat ng system
- Pagpapatupad ng engineering sa loob ng napagkasunduang saklaw ng trabaho
- Arkitektura at plano ng paglipat
- Napagkasunduan ang paglipat ng system at proseso ng pagbawi
Nakatalagang Engineering Team
Pinakamahusay para sa: Malawakang pagpapabuti ng sistema
Iniaalok ang patuloy na engineering matapos kumpirmahin ang mga espesyalista, saklaw, availability, at aktuwal na kapasidad. Walang pangakong may team na agad makakapagsimula.
Ang Kalamangan
Continuous integration at delivery
- Kumpirmadong kapasidad ng espesyalista bago ang commitment
- Napagkasunduang implementation at acceptance
- Malinaw na responsibilidad sa operasyon
Suporta Pagkatapos ng Migration
Pagkasunduan ang monitoring, updates, at maintenance responsibilities para sa bagong deployment.
Pagsubaybay ng Performance
Ihanda ang napagkasunduang monitoring at alerting.
Mga Update
Security at framework patches ayon sa maintenance scope.
