Why enterprises are modernizing Microsoft environments now

Modernization is no longer about replacing working systems. It is about ensuring they remain maintainable, secure, and adaptable for the next decade.

Several forces are converging:

  • Legacy .NET Framework systems are becoming increasingly expensive to maintain.
  • SharePoint 2013 and 2016 environments accumulate governance and customization debt over time.
  • Cloud-native architectures have become the default for scalability and resilience.
  • AI and automation initiatives expose limitations in monolithic applications.
  • Regulated organizations face growing operational resilience and compliance requirements.

The challenge:

The challenge is no longer keeping legacy Microsoft systems running. Enterprises need platforms that remain maintainable, cloud-compatible, and capable of supporting future automation and AI initiatives without introducing unnecessary risk.

How Azati uses the Microsoft Stack to resolve your business challenges

Modernize and stabilize legacy Microsoft environments

Enterprise Microsoft systems accumulate years of customizations, dependencies, and business rules. Azati helps organizations modernize these environments incrementally without disrupting critical operations.

Whether you're migrating SharePoint farms, upgrading .NET Framework applications, or untangling inherited architectures, we focus on reducing technical debt while preserving the business logic your organization depends on.

Typical engagements

  • SharePoint migration and portal consolidation

    Migrate SharePoint 2010/2013/2016 environments to Microsoft 365 while rebuilding governance, permissions, metadata, and navigation structures.

  • .NET Framework modernization

    Upgrade legacy ASP.NET and .NET Framework applications to modern .NET and cloud-native architectures.

  • Monolith decomposition

    Incrementally split tightly coupled applications into maintainable services without requiring a complete rewrite.

  • Legacy customization remediation

    Identify unsupported SharePoint customizations, workflows, web parts, and third-party dependencies before they create migration risks.

  • Enterprise document and content systems

    Modernize document-centric applications and line-of-business platforms while preserving existing workflows.

Technologies involved: .NET 8/9, ASP.NET Core, SharePoint Online, SPFx, Azure SQL, Entity Framework, GitHub Actions, Azure DevOps.

Azati specializes in Microsoft systems with history

Many modernization projects fail because the hardest part isn't technology. It's accumulated complexity:

  • Undocumented business rules
  • Inherited code from previous vendors
  • Years of SharePoint customizations
  • Fragmented governance
  • Dependencies no single team fully understands

Azati works inside these environments and helps enterprises modernize them incrementally instead of replacing them wholesale.

Business challenge

The client, a leading commercial real estate company, needed to power over 90% of online property sales across the US through a single auction platform. The core challenge was managing vast volumes of documents, images, and structured data linked to each distressed property unit available for sale. Sensitive PDF files required controlled access: only authorized buyers could view specific documents, and content had to be protected against redistribution. The project also required coordinating development and integration across multiple external vendors simultaneously, each responsible for different platform modules, while keeping releases on schedule.

Solution at a glance

Azati built a large-scale online auction marketplace incorporating an Enterprise Content Management System (ECM) and Web Content Management System (WCMS) on an ASP.NET / .NET MVC stack hosted on Azure. The platform automated document processing, applied Vitrium-based PDF security to restrict access per buyer authorization, and integrated with SpringCM for document lifecycle management. Azati played the central coordination role across multiple vendor workstreams, aligning delivery and enhancing the overall development process throughout the engagement.

How Azati solved the challenge

  • Multi-vendor development coordination and workstream alignment across the full platform
  • Vitrium integration for PDF-level access control and document redistribution protection
  • SpringCM integration for automated document lifecycle and content classification
  • Automated property data ingestion and auction listing generation pipeline
  • Sentry-based error monitoring and production observability across the platform

Business outcome

  • Secure document viewer with per-buyer authorization and PDF redistribution controls
  • ECM/WCMS handling documents, images, and structured property data at auction scale
  • Automated processing pipeline reducing manual document handling by 45–70%

  • React
  • GraphQL
  • Kubernetes
  • Grafana
  • GitLab

Business challenge

A major vertically integrated oil and gas organization needed a centralized construction cost calculation platform for large-scale industrial infrastructure projects and complex tender documentation. The pricing engine relied on interconnected catalogs, coefficients, material-resource statements, and project-specific configuration rules spanning multiple procurement workflows, where a single coefficient change could cascade across transportation costs, exclusion rules, and tender pricing outputs downstream.

Solution at a glance

Azati took ownership of implementing and stabilizing four interconnected calculation domains, pricing catalogs, coefficient logic, material-resource processes, and tender preparation workflows, while simultaneously working through inherited code from a prior vendor. The team performed deep immersion into existing undocumented business logic, validated calculation correctness across all module dependencies, and delivered two releases ahead of schedule including future functionality demos. Domain mastery of Oil & Gas construction estimation methodology, coefficient structures, limited expense calculations, transportation cost models, was a prerequisite for safe delivery in this engagement.

How Azati solved the challenge

  • Deep immersion into undocumented inherited calculation logic from a prior vendor
  • Cross-module dependency mapping across pricing catalogs, coefficients, and material-resource statements
  • Regression validation across all calculation and procurement modules after each change
  • QA for calculation-intensive workflows with domain-specific correctness verification
  • Iterative release planning with functionality demos delivered ahead of contractual schedule

Business outcome

  • Centralized pricing engine covering construction cost estimation for large-scale O&G infrastructure
  • Coefficient management system with downstream validation across all dependent calculation modules
  • Material-resource statement generation for industrial construction procurement
  • Tender preparation workflows supporting regulated O&G construction bidding processes
  • Full cross-module calculation validation preventing procurement errors and pricing inconsistencies

What is Azati's Microsoft Transformation Squad?

A dedicated cross-functional team operating inside complex Microsoft environments, from assessment through modernization and stabilization. We stay with the system after recommendations are made, helping teams modernize incrementally while preserving business continuity.

Typical squad composition

  • .NET architect
  • Senior C# engineers
  • SharePoint specialists
  • QA engineers
  • DevOps engineers
  • Delivery lead

The first sprint typically starts within 2–4 weeks.

  1. 1

    Discovery

    We start by understanding the current environment: .NET versions, SharePoint estates, Azure footprint, inherited dependencies, regulatory requirements, and operational constraints. The goal is to identify where complexity and risk actually reside.

  2. 2

    Assessment

    We document architecture, customizations, dependencies, and modernization blockers. This phase produces a practical roadmap covering risks, priorities, team composition, and an indicative migration approach.

  3. 3

    Stabilization

    Before introducing change, we address immediate risks and improve visibility. This may include regression validation, observability, documentation, performance improvements, and remediation of unsupported components.

  4. 4

    Incremental modernization

    Rather than replacing entire systems, we modernize them in stages. Applications, integrations, and infrastructure evolve gradually while preserving existing business logic and minimizing disruption.

  5. 5

    Knowledge transfer and continuity

    Documentation, engineering practices, and operational knowledge remain with your team. IP ownership stays with you from day one, and multi-year continuity is supported through overlapping team rotation.

Frequently Asked Questions

Timeline depends on the size and complexity of the SharePoint environment. A single-portal migration to SharePoint Online typically takes 4–8 weeks from assessment to go-live. Enterprise-scale consolidations of 20+ portals, like the Oil & Gas engagement in our case studies, require a structured assessment phase (4–6 weeks) followed by a phased migration program that can run 3–9 months depending on content volume, customization complexity, and stakeholder coordination requirements.

.NET Framework (versions 1.0–4.8) is Windows-only, no longer actively developed, and incompatible with modern cloud-native architectures. .NET 8 (part of the unified “modern .NET” platform, formerly .NET Core) is cross-platform, open-source, significantly faster, and receives long-term Microsoft support. For most enterprises, migrating from .NET Framework to .NET 8 reduces hosting costs, unlocks Azure-native deployment, and is a prerequisite for integrating Azure OpenAI and Semantic Kernel into existing C# services.

Yes. Azati has a legal entity in Warsaw, Poland, enabling EU-compliant delivery with data residency on Azure EU regions (Germany, France, Netherlands). We design .NET and Azure architectures with GDPR-by-default patterns: privacy-by-design service boundaries, Azure AD B2C for consent management, data subject request automation, and full audit trails. For financial sector clients, we also cover DORA-aligned operational resilience and NIS2. For AI features on Azure OpenAI, we document EU AI Act compliance requirements from sprint one.

From initial contact to first sprint is typically 2–4 weeks. This covers a scoping call, a free one-page diagnostic (current state, migration roadmap, team composition), and contracting. Teams for standard .NET modernization engagements are 4–8 engineers. Larger SharePoint consolidation programs may involve 10–15 specialists and require 4–6 weeks for the assessment phase before sprint work begins.

In practice, it means integrating Azure OpenAI (GPT-4, o3) or Semantic Kernel into existing C# services to automate tasks that previously required human judgment or manual processing. Common examples: document processing pipelines that extract and classify content at scale, back-office automation that handles exceptions and routing decisions, LLM-powered internal search across enterprise knowledge bases, and conversational interfaces for existing .NET line-of-business systems. The key is that these are production integrations, not pilots or proof-of-concepts, with clear operational objectives, audit trails, and error-handling appropriate for enterprise environments.

Yes, and it is one of the verticals where Azati has the deepest Microsoft stack experience. Our enterprise SharePoint migration and consolidation case study (see Case Studies section above) was delivered for a major Oil & Gas enterprise under strict security constraints. We understand the documentation-heavy, compliance-conscious, and operationally sensitive environment that energy sector IT operates in.
