GP to Business Central Migration (Why Waiting Until 2029 Is a Costly Mistake)

Decision-making is an important part of a business. Making the right decision at the right time truly makes a difference. Change can be difficult, but certain critical decisions need to be made early to avoid mishaps and enjoy the benefits.

One such critical decision is the Dynamics GP to Business Central migration before 2029. With the Microsoft Dynamics GP end of life, it’s time to migrate to Business Central. This is the start of your ERP modernization journey, marking a bright future ahead.

GP retirement in 2029 seems to be a long-term, distant plan, but its implications can be seen today. Using the Great Plains ERP system is no longer beneficial, and it is imperative to take the necessary steps to move away from it; otherwise, there is very little time left, and the implications of the delay will be harmful.

When you avail Business Central migration services, it takes 9-18 months, and the sooner you start, the sooner you get results. Choosing a BC migration partner allows business to migrate without any errors and inconsistencies.

When Does Microsoft Dynamics GP Reach End Of Life?

The Microsoft Lifecycle Policy indicates that Dynamics GP’s end of life is December 30, 2029.

Business Central takes its place as Microsoft announces that it’s the ERP for all SMBs. This change is positive because Microsoft chooses innovation and advancement, and so should businesses.

Businesses that choose the Microsoft Business Central upgrade should not worry about change, as Dynamics 365 consulting partners are ready to help in implementing the system. So, it’s better not to wait for the end date and step into a world of transformation and advancement.

What Happens If You Don’t Migrate Before 2029?

So with the Microsoft Dynamics Great Plains end of life, you are vulnerable to loss and introduce new risks that can disrupt your business. The risks are related to security, compliance, partner availability, and crisis management.

The longer you wait, the more you lose.

Security Vulnerability

So, as Microsoft has announced the discontinuation of the system, it will no longer offer security updates. If your business encounters a problem, it will remain unresolved.

Compliance Issues

As the Dynamics GP lifecycle is discontinued, compliance will no longer be offered. If you belong to an industry that needs strict compliance, then your business is at stake.

Partner Availability

Partners will also move from GP to BC migration, and they will no longer offer support as the Dynamics GP support end dates are announced. As the Business Central Partner

would be occupied with clients who need implementation, you might miss out on a reliable partner who is busy with another project.

Migration Risk

If you do not plan to migrate on time, you miss out on partner availability. This leads to a risky migration, and you end up in a crisis.

So, planning on time is essential. The delayed ERP migration will cost you a lot, as you will rush the implementation and miss essential resources needed for the migration.

GP vs Business Central: What’s Actually Different?

The first question that pops into your mind is: why is Business Central, not GP? For Thai, you need to understand the difference between Microsoft Dynamics GP and Dynamics 365 Business Central.

The biggest shift is the move from cloud to on-premises across both systems. Dynamics GP is installed on the business’s own servers, while the cloud is over the internet.

GP offers manual updates, whereas the cloud offers automatic updates. The updates are expensive and disruptive in GP, but not in the cloud.

GP requires higher maintenance costs, whereas Business Central is cost-effective. Moreover, Dynamics GP has a rigid structure that is difficult to customize, whereas Business Central is flexible.

Why Business Central Is GP’s Natural Successor

Business Central is the successor to Dynamics GP and Dynamics NAV, as it has shifted to the cloud and offers greater flexibility and ease of use. It seamlessly integrates with the Microsoft products, offering seamless data flow across applications.

Power BI and Power Automate integration help you automate and handle finance without any hassle. The fundamental problem was the GP upgrade due to a version lock. Business Central offers extension-based customization that eliminates this issue.

What Data Is Migrated

Data migration is performed using Microsoft-provided tools. The data migrated includes master data, system data, transactional data, historical data, and classes for customers, vendors, and items.

The data migration time is not fixed as it depends on the amount of data being migrated. It is significant to avoid migrating data to the production environment that is already in use. This will result in overwriting data that is useful to the business.

During the GP to D365 BC migration, data is migrated from table by table, and each table is tracked to avoid mistakes or inconsistencies. The tables and schema need to match for data migration.

This is why migrating the data to a sandbox environment and then moving to the production environment is necessary.

How Long Does a GP-to-BC Migration Take?

The next big question is the timeline. The most frequently asked question is how long it takes to implement the system. There is a rough estimate of 4-24, but it depends on what the business wants and how.

Customization, modules, features, and advanced Microsoft Dynamics 365 Business Central integration all play a role in determining the time.

For Small business

Small businesses that need basic and core processes may require 4-9 months to install the system.

Mid market

Mid-market enterprises need 9-14 months with customization, extensions, integrations, and

Complex system

If a business has complex processes and unique workflows, it needs proper data migration, multi-currency support, and entity support, which can take 12-24 months.

Waiting for the deadline is miscalculation and mismanagement, as it will cost you a lot in the long run. You will have to wait for the partner to be free, pay more, and deal with a system that is no longer reliable.

It’s better to plan early to avoid bottlenecks that can get in the way of your success.

What Does It Cost to Migrate from GP to Business Central?

The cost of the migration also depends on what you want and the scope of your project. But we will break down the cost to help you understand it, so you can make a realistic budget.

Why Starting Now (Not 2028) Is the Smart Move

So, when I say start now, I mean it’s urgent. You need to understand the urgency of the situation you are in. It is not optional to delay the migration and keep using the outdated serum.

When Microsoft 365 SMB ERP discontinues a product, you must understand that it is no longer relevant today. It has already aged, and if you continue to use it, you will be at a loss.

If you start your GP-to-D365 BC migration in 2026, you are more likely to succeed early.

You will complete the business using it today, but the longer you delay, the further behind you will fall. As you waste a year, you stay years behind your competitors.

Partner Availability

The first thing you should note is that you need a partner to implement the system. And their availability is important. All businesses will acquire the best Microsoft Dynamics 365 ERP consulting partner, and if you are late, your preferred Dynamics 365 partner will already be booked, so you won’t get their services. Thai will put you in a problematic situation.

Implementation Cost

The biggest concern is Dynamics 365 Business Central implementation cost. When you are migrating, you need to invest. Right now is the best time to get the best prices. Later, the demand will create issues, and you will have to pay more to get the same services.

Transition On Your Terms

If you migrate now, you can plan everything accordingly. You get the right resources, and the availability is ensured. The delay will not give you what you want.

A Competitive Asset

Modernizing right now means competing with those who are doing the same. If you don’t do it now, you will be left behind.

Starting today means you need 10-14 months; after that, you will see results. So it’s all about collaboration today that will give you the benefits in the future.

How to Start Your GP to Business Central Migration

Now the question is: how to start the GP-to-Business Central migration? And the answer is simple: you need to follow the step-by-step process to get where you want to go.

Internal Assessment

The first step is to assess your current GP environment and document it. Extensions, integration, user, everything.

Microsoft Partner Selection

Choosing a partner is the most critical decision. You need to choose wisely, as not all of them have the experience of GP migration. Ask for demos, hold meetings, discuss scope, review feedback, and then select the partner.

Data Migration And Configuration

The next step is data migration, and you need a data migration strategy. The first step is to migrate the master data; then migrate the historical and other data.

Phased migration is better for migrating historical data over time.

User Acceptance Testing And Training

Change management is an essential part of the migration. Get the teams the relevant training, rather than just limited workshops that don’t answer all their questions.

Go-live And Hypercare

Test the system in the sandbox environment for a smoother go-live. Also, the partner must offer hypercare initially to mitigate issues that may arise after going live.

Tips To Choose The Right Business Central Partner

As we have already discussed, partner selection plays a major role in the migration, so you need to make the decision very carefully. One of the reasons why Out-of-Box Business Central Fails is that the partner is not competent.

The Business Central partner must possess the following qualities:

Proven Experience

Not all partners are reliable because they lack migration experience. So you need to find a partner who has GP migration experience.

Industry Experience

Then comes the industry experience. Choose a partner who knows your industry, understands workflows, and offers solutions accordingly. We are not looking for generic solutions.

The right partner also rescues a failed Business Central Implementation.

Post Implementation Support

Post implementation Business Central support services are very important, and you should take it seriously. If you miss this, it will cost you in the long term. Implementing the system is not enough. Running it stably is what you need to be successful.

Transparent Pricing

Many Dynamics partners are not transparent with the pricing. Ask them about the price and try to avoid hidden changes that cost you in the long term. Pricing affects your implementation, so make it clear from the beginning.
