Key considerations for updating your legacy systems
Upgrading legacy systems isn’t just challenging, it can also be quite complex.
We won't break down every factor that goes into the process in this short article, but adopting the following principles can help inform some of the decisions you’ll face along the way.
Think about the future. Today.
The environment around you today will influence your decisions, but in a few years you'll probably need to adapt your processes and technology once again to suit the new landscape.
While SaaS platforms provide API’s, webhooks, and other integration tools to make it easier than ever before to migrate systems, you should ensure your choices are well-informed by doing your research.
- Is the technology solution you’re considering well supported and updated regularly?
- How well funded is the vendor, and can they demonstrate ongoing investment in their roadmap?
- Are there positive case studies from real-world implementations showing how the technology delivers against the vendors promise?
- How will the new system fit into your wider technology / business roadmap?
Technology is just an enabler
Even though your business relies on technology, upgrading your legacy systems shouldn’t be a technology-led process.
Focus on identifying the problems you’re trying to solve, as well as the outcomes you want to achieve - look for tools that will help you achieve those outcomes.
With these principles in mind, you can then start the process of upgrading your legacy systems in three stages.
The 3-step legacy system replacement strategy
Step 1 - Do a thorough technology evaluation
It’s impossible to understand the impact of any changes you might make without a good audit of the systems in place, how they're performing, how they work together, and what the people that use them think of them.
To achieve this, you need to do a technology audit.
You need to consider the business processes that the technology supports and the integrations that are in place to ensure that any changes don’t have unexpected, and unfortunate, consequences.
Step 2 - Identify the problems
Look at support tickets and speak to users to identify legacy system pain-points.
Track the flow of data and dependencies between different tech stacks to identify the root cause of the problem.
You might find, for example, that issues in your call centre’s case management system might be helped by improving the integration and data capture from upstream systems such as your company’s website.
Step 3 - Plan and execute systematic change
While a total transformation and replacement of systems can be the optimal way to solve legacy issues, it’s not always financially or logistically viable - or even necessary.
You could consider the incremental replacement of technology over time or retro-fitting API integration tiers so that legacy systems can be swapped out further down the line.
If any of these introduce too much risk or expense, then you could simply maintain the status quo. When you’re in a position to move forward, at least you’ll have the information you need about your systems and from where your problems stem.
