Maintenance and license costs increase and drain your budget.
You can’t scale: on-prem gear hits a hard limit, and new servers take ages to buy.
System compliance boundaries block effective change and slow releases.
Teams repeat legacy patterns. Rewrites take forever, burnout grows.
Legacy setups miss modern security and audit standards.
Since 2007, Corsac has helped 100+ clients modernize, from data migration to cloud to rebuilds. We meet your compliance needs, preserve the features users rely on, and run safer on-prem-to-cloud cutovers.

38%Corsac’s moving from server to cloud infrastructure turns change into growth. We modernize with minimal disruption, keep operations steady, meet compliance, and give your team a scalable base to build fast.
Cut overhead costs with a transparent, usage-based model.
Scale the system when demand changes.
Improve ROI by shifting CapEx to performance-linked OpEx for flexible budgets and financial clarity.
Automate the busywork: fewer errors, faster releases. Clear metrics = quicker decisions.
Turn changes into long-term competitiveness, deep customer trust, and regulatory confidence.
We decouple and refactor apps off physical servers, file shares, and legacy middleware.
We orchestrate a hybrid run so on-prem and cloud run in parallel.
We migrate and validate data via staged replication and checks.
We enforce zero-trust IAM with full audit trails.
We automate provisioning with infrastructure-as-code and safe rollbacks.
Let us help you rebuild what’s holding you back.
Corsac makes your moving from on-premise to cloud infrastructure calm and predictable. We map dependencies, meet compliance, cut over in phases, and keep hybrid stable so work never slows or drops.
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
Your aging system drains your business resources through slow hiring, security gaps, and delayed launches. We reduce these “dark tech debt” losses before they impact your revenue.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
Modernization efforts will be ineffective if the core issue is institutional rigidity. We reveal hidden limits and help grow with flexibility.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
Legacy servers rely on outdated operating systems, firmware, and drivers. On-prem to cloud transition consulting identifies “invisible” technical debt that increases maintenance complexity. Breaks happen quietly, delaying fixes and slowing business-critical software updates.
Electricity, cooling, and physical repairs add up. Any hardware failure can freeze operations and disrupt customer commitments, because older hardware often lacks redundancy.
Scaling on-premise infrastructure requires significant lead time, capital expenditure, and physical space. Your business can’t support user growth or new services without costly downtime.
On-premise systems depend on rare experts. Losing them can stop updates and block essential workflows, risking business continuity. On-premise to cloud migration consulting mitigates this dependency.
Old infrastructure misses modern protections and doesn’t align with modern zero-trust standards. Data breaches or audit failures create regulatory compliance risks and damage client trust.
Rigid environments prevent automation, cloud integration, and AI adoption. Teams stay stuck on survival work instead of product evolution.
Our team helps companies navigate on-prem to cloud transition consulting with approaches tailored to their business:
A controlled first step in on-premise to cloud migration. Our team ensures a thorough pre-migration audit, simulates the live environment, and validates performance post-migration to guarantee stability.
We move applications to the cloud while making small adjustments to leverage cloud-native features. With our on-prem to cloud transition consulting, this approach improves efficiency while avoiding full re-architecture.
Best for systems that are holding the business back but need to unlock scalability or enable AI and analytics capabilities. We lead on-premise to cloud migration that replaces brittle architecture with scalable foundations.
We migrate legacy databases that are often the backbone of enterprise operations. We manage schema conversions, replication, and performance tuning, while ensuring compliance and minimal disruption to live operations.
When full cloud isn’t an option, we design hybrid architectures that integrate legacy systems and cloud services seamlessly, with reliable networking, security, and monitoring across environments.
Our team audits hardware, workloads, licenses, and compliance. Then we map dependencies, quantify involved risks, and prioritize workloads to build a factual migration baseline.
Plan of a step-by-step move goes next: run hybrid, sequence changes, and keep rollback ready. Each choice ties to outcomes that include lower maintenance, stronger resilience, and clear ownership.
We plan on-prem to cloud moves with transparent estimates: structured, low-risk, with CI/CD gates aligned to your cadence.
We run on-prem and cloud in parallel until validation to preserve continuity and compliance.
We choose the proper stack (AWS, Azure, GCP, or hybrid. Then we replatform/refactor where it pays off.
We migrate data with staged replication, checks, and a tested rollback.
Then, update architecture schematics, tooling docs, runbooks, integrations, and train your team so they can use it.
Once live, we tune workloads, automate deployments, and add guardrails to prevent new tech debt. Reviews align compliance, performance, and costs. We transfer knowledge and train your internal team.

We focus on modernization for companies unable to grow due to aging systems
We replace only what must be changed, protecting your investment and CTO’s credibility.
HIPAA, HL7/FHIR, SOC2, GDPR, ISO compliance is integrated into every stage.
Integrating into your Git, CI/CD, and workflow tools, we make modernization visible, testable, and traceable
We uncover hidden costs, feature delays, and security gaps and offer ways of their removal
By providing CEOs stakeholder-ready roadmaps and progress metrics, we enable well-grounded transformation
They fulfill your task without seeking to address the issue at the root
Dispersing the focus, they fail to meet specific Healthcare G and other industry requirements
Generalized practices, regardless of the product, team, or business specifics
Initiate full rewrites instead of using the working parts and considering business context
Insufficient collaboration leads to poor handover, with documentation debt and weak enablement.
Development happens in isolation, prioritizing code delivery over actual business value.
The process of “on-prem to cloud migration” is when we move applications, workloads and data out of your data center to a cloud platform. When done correctly, it reduces the maintenance costs, allows to scale up easily, and enhances the reliability without interfering with your work.
First, we run a readiness assessment and roadmap. Then, Corsac experts design the target architecture, schedule staged cutovers, migrate, test, and optimize costs along with performance. The system you get from us is compatible with HIPAA/GDPR/SOC 2/ISO 27001. After all, we share the knowledge with your team so they can run it.
We copy data to the cloud in stages while your system stays live. We keep both sides in sync, verify accuracy, and switch only when they match. A tested rollback is ready, so if anything’s off, we promptly flip back, and users can go on using your product.
At Corsac, we follow the proven way: assessment and roadmap, architecture and planning, migration execution and integration, then optimization and governance. Each step has clear milestones, validation, and reporting.
Cost depends on your specific scope, data volume, compliance needs, and refactoring level. We provide a precise estimate after readiness analysis, plus projected ROI, so you can compare OpEx vs CapEx. Reach out to us to know exactly your price.
