Finance and operations: Migrating legacy ERP to the cloud

Finance and operations: Migrating legacy ERP to the cloud

Your old ERP system is still in operation. And although it feels a little slow and dated, it’s still working, and your teams know how to use it. However, as you grow - and as your competitors adopt newer technology - cracks might begin to show in your business processes causing you to lose your competitive edge.

If you’re looking ahead to cloud-based ERP solutions, you can get ahead of the curve before any major incidents bring your business to a halt. But aside from avoiding technical catastrophe, what else should you expect from a modern ERP system? In this blog, we explore.

Why migrate your legacy ERP to the cloud?

Scalable, portable and mobile

Legacy systems rely on hardware and infrastructure that has to be installed and managed onsite. If you want to relocate or expand, you need to take it all with you or add more components. If you need extra storage, more users logging in and mobile accessibility, you’ll be forever bolting on more physical hardware and upgrading software manually. Working in the cloud gives you both the scalability and portability that a growing business needs. 

In the cloud, you’re not restricted by how much infrastructure you can invest in and maintain on your premises. This means if you want to extend your ERP into previously unreached areas of your business, you can upgrade quickly and can add new functions for areas such as supply chain management, warehouse management, e-commerce and your CRM without slowing down the whole system or overwhelming it completely.


Your legacy system may have been built with a proprietary programming language. This makes it difficult to customise and maintain as support for your system dwindles into obscurity. 

You’ll also have a much faster route to incorporate IoT, AI and Machine Learning capabilities due to the increased processing power and storage that the cloud offers.

Cost benefits of migrating your resource planning to the cloud

Any changes in your IT environment requires investment. But it’s the level of investment and how quickly you’ll see a return that counts. The risk of leaving an upgrade too late is at best a gradual slowing of productivity across the business, at worst, a major incident causing devastating downtime. If you’ve decided that now’s the time to investigate a move to the cloud, consider the following benefits:

  • Lower upfront costs vs hardware expansion (low cost of entry)
  • Manageable subscription fees (fixed monthly costs)
  • Lower IT project costs (upgrades and bug fixes are rolled out automatically)

Add to this the ability to take your ERP with you if you relocate without that becoming its own project and the ease at which you can increase the number of users, the cloud option becomes a clear financial winner.

3 tips for a successful ERP cloud migration

Even if you’re convinced it’s time for a change, it can be difficult to get buy-in from key stakeholders. You might be asked how the migration will affect uptime and how safely it can be done. Here are a few top tips for peace of mind.

  1. Planning: Plan for a phased migration. This means keeping your legacy infrastructure running while units are moved from your current environment to the cloud. This helps limit risk and ensures your legacy system is still available for use while you transition.
  2. Performance auditing: Before, during and after the migration, you need a deep understanding of current capacity, needs, requirements and success measurements. This helps you plan your requirements list before you choose your new solution, test for performance during migration and assess success post-implementation.
  3. Exploit new potential: There’s a tendency to simply pick up what you have and drop it into the cloud. But since you are going through a transformation anyway, now is the perfect time to look for opportunities to further improve workflows, applications and security.
