Microsoft D365 Implementation: Moving From Legacy Systems to the Cloud With Intwo

Microsoft D365 implementation is the process of moving a business from traditional, often fragmented CRM and ERP systems to Microsoft Dynamics 365, a modern cloud-based suite of intelligent business applications. Done well, it streamlines processes, improves customer engagement, strengthens data visibility, and gives teams analytics they can act on. Done poorly, it disrupts daily operations — which is why most organisations choose an experienced partner rather than attempting the move alone. Microsoft D365 implementation services from Intwo are designed around that reality: the company positions itself as a strategic implementation partner that evaluates the current state of your CRM and ERP applications, then suggests tailored solutions aligned with your business objectives. For businesses weighing up a Microsoft D365 implementation, this guide explains what the service covers, how Intwo approaches it, and what to ask before you begin.

What Microsoft D365 implementation covers

Demand for Microsoft D365 implementation services has been rising with the rapid adoption of cloud-based solutions, the growing popularity of AI, demand for better business analytics, and the ever-present need for stronger customer engagement. Microsoft Dynamics 365 brings these capabilities together in one cloud ecosystem, replacing legacy systems with applications that scale. For most organisations, a Microsoft D365 implementation is also the first time sales, service, and reporting data sit in one connected place, which changes how quickly teams can make decisions.

A comprehensive Microsoft D365 implementation typically covers every stage of that move:

• Planning and strategy based on the current state of your CRM and ERP applications
• Configuration of bespoke Dynamics 365 CRM modules matched to your processes
• Secure migration of data from existing systems
• Integration with third-party systems and the rest of your Microsoft applications
• User training, post-implementation support, and ongoing maintenance

The goal of Microsoft D365 implementation is not simply to install software. It is to reshape how the organisation works — unifying data, automating routine tasks, and creating a platform that supports growth rather than restricting it.

Why partner with Intwo for Microsoft D365 implementation

Intwo is a certified Microsoft Solutions Partner and, as stated on its site, a Microsoft Inner Circle Partner for Business Applications — a strong credential signal in a market full of generalist providers. Beyond certification, the company outlines seven reasons businesses choose it for Microsoft D365 implementation projects:

• Bespoke solutions. Every Microsoft D365 implementation is custom-built around the client’s needs rather than a fixed template, and Intwo works with businesses of all sizes.
• Comprehensive delivery. The package covers the full migration journey, including extensive customization plus post-implementation support, maintenance, and training.
• A proven track record. Intwo cites a long list of successful Microsoft D365 implementation projects and happy clients — a claim the company makes on its own record.
• Global support. Certified professionals manage complex deployments, including multi-country roll-outs, with precision and consistency.
• Seamless integration. Solutions connect with the wider ecosystem of Microsoft applications while maintaining a unified, secure environment.
• Diverse industry experience. From SMEs to large enterprises with complex challenges, Intwo brings cross-industry delivery experience to each Microsoft D365 implementation.
• Dedicated support. Round-the-clock assistance keeps systems performing optimally so internal teams can focus on the work that drives growth.

Together, these strengths frame Microsoft D365 implementation with Intwo as a consultative partnership — strategy alongside hands-on technical work — rather than a simple product installation.

Six services inside every engagement

Intwo’s published service list for Microsoft D365 implementation covers six core areas:

1. Business process optimization and analysis, used to craft bespoke implementation solutions rather than force generic ones.
2. Bespoke Dynamics 365 CRM modules, configured to match your exact requirements.
3. Seamless, secure data migration from existing systems to Microsoft Dynamics 365.
4. Third-party integration, connecting external systems and applications without interrupting business as usual.
5. User support and training, described by Intwo as top-of-the-line enablement for client teams.
6. Timely updates and ongoing maintenance, keeping the Dynamics 365 environment running optimally at high security standards.

Together, these six services span the full lifecycle of Microsoft D365 implementation, from early process analysis to optimization after go-live. In practice, this means a Microsoft D365 implementation with Intwo runs from the first process workshop through go-live and into day-to-day operation, instead of ending at deployment.

How data migration is handled

Data migration is the highest-risk stage of most Microsoft D365 implementation projects, and Intwo follows a structured, five-step approach:

Step one: assessment and planning. Experts assess existing systems to understand dependencies, formats, and constraints, then build a detailed implementation strategy aligned with your business objectives.

Step two: data mapping and cleansing. Data fields are mapped to the corresponding entities in Dynamics 365, while inconsistencies, duplicates, and unwanted records are identified and cleaned for a more efficient dataset. Clean, deduplicated data also makes reporting in the new system far more reliable from day one.

Step three: automating the migration. Purpose-built tools and technology automate the transfer, reducing manual effort and the errors that come with it. For a complex Microsoft D365 implementation, that automation keeps large datasets moving accurately at speed.

Step four: testing and validation. Before go-live, multiple test cycles validate data accuracy, field mapping, and system behaviour — the most important checkpoint in the process.

Step five: go-live support and audit. After migration, a post-migration audit verifies data integrity and confirms the new cloud ecosystem is performing as expected.

This time-tested method keeps Microsoft D365 implementation migrations secure, verifiable, and reversible at defined checkpoints.

Costs, timelines and flexibility

Intwo is deliberately honest about two of the most common Microsoft D365 implementation questions: how long it takes and what it costs. There is no fixed answer for either, because both depend on the scope of the project, the scale of the business, the level of customization required, and the amount of ongoing support needed. Instead of generic figures, Intwo’s teams assess your requirements and provide a realistic timeline estimate and a tailored quote. Because every Microsoft D365 implementation differs, those answers are scoped after an assessment rather than guessed online.

Flexibility also extends to delivery models. A Microsoft D365 implementation can be structured as a full-project implementation, a phase-wise rollout, or a module-by-module implementation, so organisations can match the approach to their budget, risk appetite, and internal capacity.

Security and support after go-live

Security receives explicit attention throughout delivery. Intwo states that it follows industry best practices during Microsoft D365 implementation, applying secure access controls, encryption, and other robust measures to protect business data against internal and external vulnerabilities. Handled this way, security in a Microsoft D365 implementation covers the project itself and the cloud environment that follows it.

After deployment, the relationship continues: extensive post-implementation maintenance, timely updates, regular maintenance checks, and 24/7 support keep the Dynamics 365 suite running smoothly. Structured training and smooth knowledge transfer empower client teams to manage the platform confidently — the final ingredient that turns a Microsoft D365 implementation from a one-off project into a durable operational advantage.
