How to Switch Dynamics 365 Implementation Partners Mid-Project
Changing your Dynamics 365 implementation partner in the middle of a project can feel risky. You may already have invested months in discovery, configuration, integrations, data migration and custom development.
However, continuing with the wrong implementation partner can sometimes create even greater risks.
Missed deadlines, uncontrolled costs, poor communication, repeated technical issues and unclear project ownership can turn a Dynamics 365 implementation into a difficult and expensive programme.
The good news is that changing your Dynamics 365 partner does not necessarily mean starting the entire implementation again.
With the right transition plan, a new partner can assess the existing project, identify what should be retained, resolve critical issues and build a realistic path towards go-live.
This guide explains when you should consider switching Dynamics 365 implementation partners, how the transition works and what to check before appointing a replacement partner.
Can You Change Your Dynamics 365 Implementation Partner?
Yes. Organisations can change their Dynamics 365 implementation partner if the current relationship or project is no longer delivering what the business needs.
A partner change may happen during implementation, after go-live or while moving into another phase of the Dynamics 365 programme.
The more important question is not whether you can change partners, but whether switching is the right commercial and technical decision.
Before making the change, businesses should understand:
- What has already been delivered
- What remains incomplete
- The quality of existing configurations and customisations
- Current project risks
- Data migration status
- Integration dependencies
- Contractual commitments
- Documentation available
- Access to environments and source code
- Internal business priorities
An independent Dynamics 365 project assessment can help establish the condition of the project before you decide what to do next.
8 Signs It May Be Time to Switch Dynamics 365 Partners
Not every project problem requires changing partners. Large ERP and CRM implementations naturally encounter challenges.
However, several recurring issues may indicate a deeper problem.
1. Project Milestones Are Continuously Missed
One missed milestone may be manageable.
Repeated delays without a clear recovery plan are more concerning.
Your implementation partner should be able to explain why delays have occurred, what dependencies are affected and how the project will be brought back under control.
2. Project Costs Keep Increasing
Dynamics 365 implementation costs can change when scope or requirements change.
The problem begins when costs continually increase without transparent explanations.
If change requests, additional consulting days and unexpected development repeatedly push the project beyond budget, review the original scope and commercial model.
3. Communication Has Broken Down
Successful Dynamics 365 implementations require close collaboration between the customer and implementation partner.
Warning signs include:
- Slow responses
- Unclear responsibilities
- Inconsistent project updates
- Problems being repeatedly escalated
- Decisions not being documented
- Different consultants providing conflicting advice
Poor communication can quickly turn technical issues into larger project risks.
4. Your Partner Does Not Understand Your Business
Dynamics 365 should support your business processes rather than simply replicate your existing software.
Your implementation team should understand how areas such as finance, operations, inventory, manufacturing, projects, sales or customer service actually work within your organisation.
A lack of industry or operational understanding can result in unsuitable configurations and unnecessary customisation.
5. Too Much Custom Development Is Being Recommended
Dynamics 365 is highly configurable, but custom development should have a clear business justification.
If almost every requirement results in another customisation, it is worth asking whether standard Dynamics 365 functionality, Power Platform or a different process could achieve the same objective.
Excessive customisation can make future upgrades, testing and maintenance more complicated.
6. Critical Issues Remain Unresolved
Repeated bugs, unstable integrations, incorrect configurations or recurring data issues can indicate that the project requires deeper technical review.
Fixing individual symptoms without identifying the underlying cause can consume both time and budget.
7. There Is No Clear Route to Go-Live
At any stage of implementation, stakeholders should understand what needs to happen before deployment.
If your project has been running for months but there is still no clear view of:
- Remaining scope
- Testing
- Data migration
- Training
- Cutover
- Go-live readiness
the implementation may need to be reassessed.
8. Confidence in the Project Has Been Lost
Sometimes the technology itself is not the biggest issue.
Senior stakeholders, key users or project sponsors may simply have lost confidence in the implementation.
When that happens, continuing without addressing the underlying causes can make user adoption and decision-making increasingly difficult.
Should You Rescue the Existing Project or Start Again?
Changing your Dynamics 365 implementation partner does not automatically mean reimplementing Dynamics 365.
A new partner should first assess what is already in place.
| Option | When It May Be Suitable |
|---|---|
| Continue the existing implementation | Core architecture and configuration are sound |
| Project rescue | The project has problems but much of the existing work can be retained |
| Partial redesign | Specific areas require significant changes |
| Reimplementation | Fundamental design, data or customisation decisions make recovery impractical |
The right approach depends on how far the implementation has progressed and the quality of the work already completed.
A good replacement partner should not recommend rebuilding everything simply because they did not create the original solution.
The objective should be to protect usable investment while correcting decisions that could create long-term problems.
How to Switch Dynamics 365 Implementation Partners
A structured transition can significantly reduce disruption.
Step 1: Review Your Existing Contract
Before making a formal change, understand your contractual position.
Review areas such as termination clauses, outstanding fees, intellectual property, source code ownership, notice periods and handover obligations.
Your legal and procurement teams may need to support this process.
Step 2: Secure Access to Your Dynamics Environment
Make sure your organisation has appropriate access and control over relevant systems.
This may include:
- Dynamics 365 environments
- Microsoft Power Platform
- Azure resources
- Dataverse
- Integration platforms
- Source code repositories
- Development environments
- Documentation
- Third-party applications
Avoid reaching the transition stage and discovering that important technical assets are controlled only by the outgoing supplier.
Step 3: Gather Project Documentation
Collect as much project information as possible.
Useful documentation includes:
- Requirements
- Solution designs
- Fit-gap analysis
- Project plans
- Customisation specifications
- Integration documents
- Data migration mappings
- Testing results
- Outstanding issue lists
- Change requests
- Training materials
Incomplete documentation is not necessarily a reason to abandon the project, but the new partner needs to know what information is available.
Step 4: Arrange an Independent Project Assessment
Before asking another partner to continue delivery, give them an opportunity to assess the implementation.
The review should consider both technology and project governance.
Typical areas include:
- Solution architecture
- Configuration
- Customisations
- Integrations
- Security
- Data migration
- Reporting
- Testing
- Performance
- Project scope
- Budget
- Timeline
- Resource requirements
The result should be a practical recovery plan rather than simply a list of problems.
Step 5: Decide What Should Be Kept, Fixed or Rebuilt
The new Dynamics 365 implementation partner should classify existing work into clear categories.
Keep: functioning components that meet requirements.
Fix: areas that are broadly correct but need remediation.
Replace: components where redesigning is safer or more efficient than continuing.
This approach can help avoid wasting investment already made in the project.
Step 6: Create a Transition and Recovery Plan
Once the assessment is complete, agree on priorities.
A Dynamics 365 project recovery plan should define:
- Immediate risks
- Critical fixes
- Revised scope
- Responsibilities
- Resource requirements
- Budget
- Key milestones
- Testing
- Data migration
- Training
- Go-live plan
Avoid simply restarting delivery without resolving the reasons the original project went off track.
Step 7: Complete Knowledge Transfer
Where possible, arrange structured knowledge transfer between the existing partner, internal team and replacement partner.
The transition should cover both technical knowledge and outstanding business decisions.
Good knowledge transfer can reduce duplicated discovery work and help the replacement partner understand why previous decisions were made.
What Should You Look for in a Replacement Dynamics 365 Partner?
Do not select a replacement partner purely because they promise to fix the project quickly.
Look for evidence that they can manage the specific situation you are facing.
Consider:
Dynamics 365 expertise
Check their experience with the applications involved in your project, whether that is Business Central, Finance, Supply Chain Management, Sales, Customer Service, Field Service or Power Platform.
Project rescue experience
Taking over an existing implementation is different from starting a new project.
The partner needs to be comfortable reviewing another team's work objectively.
Industry understanding
Industry experience can reduce the time required to understand operational processes and requirements.
Technical capabilities
Complex implementations may involve Azure, Dataverse, Power Platform, third-party applications and multiple integrations.
Make sure the replacement partner has the required technical resources.
Transparent communication
Agree on project governance, escalation routes, reporting and decision-making before restarting delivery.
Realistic recovery planning
Be cautious of any partner promising an immediate fix without first assessing the existing environment.
Questions to Ask a New Dynamics 365 Implementation Partner
Before selecting a replacement provider, ask:
- Have you previously taken over Dynamics 365 projects from another partner?
- How will you assess our current implementation?
- How will you determine what can be retained?
- How do you identify problematic customisations?
- How will you review integrations and data migration?
- What information do you need from our existing partner?
- How will you estimate the remaining project cost?
- What does your project recovery methodology look like?
- How will risks and scope changes be managed?
- Who will be responsible for the project after the transition?
The answers can tell you considerably more than simply comparing day rates.

Frequently Asked Questions
Can I change my Dynamics 365 partner during implementation?
Yes. A business can change Dynamics 365 implementation partners during a project. Before switching, review the existing contract, system access, documentation, completed work and remaining scope so the transition can be properly planned.
Do we have to start the Dynamics 365 implementation again after changing partners?
Not necessarily. A replacement partner can assess the existing configuration, customisations, data and integrations to determine what can be retained. A complete reimplementation should normally be considered only when there are fundamental problems with the existing solution.
What is Dynamics 365 project rescue?
Dynamics 365 project rescue is the process of assessing a delayed, stalled or problematic implementation and developing a plan to stabilise and complete it. This may involve correcting configuration, redesigning selected areas, resolving integrations, improving project governance or changing the delivery approach.
How long does it take to switch Dynamics 365 implementation partners?
There is no fixed timeline. It depends on project complexity, documentation, system access, outstanding work, integrations and how easily knowledge can be transferred from the existing implementation team.
What should a new Dynamics 365 partner review first?
The new partner should normally review project scope, solution architecture, configurations, customisations, integrations, data migration, testing, project governance, outstanding risks and the remaining path to go-live.
Can a new Dynamics 365 partner take over customisations built by another company?
In many cases, yes, provided the organisation has the required access and rights to the relevant code and technical assets. The new partner should review existing customisations before deciding whether they should be retained, modified or replaced.
