Why Manufacturers Look at Legacy Modernization
Many manufacturers still use old systems to manage core operations. These legacy applications often run on outdated hardware. They use old software platforms. They are hard to update and support. This slows down the business.
Legacy systems do not support new technologies well. They block efforts to improve speed, security, and performance. That is why more companies are now considering Legacy Application Modernization Services. They want to move to better platforms, especially cloud-based
systems.
There are two main ways to do this. One is Lift & Shift. The other is Re‑architecting. These paths solve
different problems.
This blog explains both. It helps you pick the one that suits your company.
What Is Lift & Shift?
Lift & Shift is also known as rehosting. It means moving your app to a new place without changing how it
works. Most companies move the system to the cloud. But they keep the same setup.
This approach is fast. It is easy to start. It works well when you want to reduce hardware risk and cut hosting costs.
Benefits of Lift & Shift
- No change to app structure
- Fast migration process
- Works well for simple apps
- Keeps downtime low
- Budget-friendly in the short term
Drawbacks of Lift & Shift
- Old problems stay in the system
- Poor use of cloud features
- No performance boost
- Future upgrades can be hard
Lift & Shift helps when time is short and the risk must stay low. But it does not help if your app needs to
scale or improve in performance.
What Is Re-Architecting?
Re‑architecting is also called refactoring. It means changing the code and structure of your app. You build the system in a way that fits modern needs. This often includes cloud features and new tools.
This path is harder but more useful in the long run. You get better speed, more control, and easier upgrades.
Benefits of Re‑architecting
- Uses cloud power like autoscaling
- Improves app performance
- Makes the system easier to manage
- Removes technical debt
- Prepares for future changes
Drawbacks of Re‑architecting
- Needs more time
- Costs more money
- Requires special skills
- Some disruption may occur
Re‑architecting legacy applications is best when the app is complex. It helps when long-term success matters more than short-term speed.
When Should You Use Each Approach?
| Feature | Lift & Shift | Re‑architecting |
|---|---|---|
| Time Needed | Short | Long |
| Cost | Low upfront | High upfront |
| Code Changes | None | Many |
| Cloud Benefits | Limited | Full |
| Risk Level | Low | Medium |
| Long-Term Value | Moderate | High |
How to Choose What Fits Your Needs
- Business Goals: Do you want fast cost savings or long-term performance gains?
- Application Complexity: Is the system simple, or does it have many layers and links?
- Timeline and Budget: Can you invest more now to save later, or do you need results fast?
- Team Skills: Do you have in-house support to rebuild parts of the system?
- Risk Tolerance: Are you open to more change now for bigger benefits later?
Other Strategies Besides Lift & Shift and Re‑architecting
You are not limited to just two paths. There are more ways to modernize legacy systems.
- Replatforming: Move to a better platform without changing the app much.
- Refactoring: Improve the code without a full rebuild.
- Replace: Use a new tool or SaaS platform instead of the old one.
- Retain: Keep the app as is and modernize later.
These paths may work better when your system does not need much change, or when a new tool offers more value.
Why Hybrid Models Work Well
Sometimes it helps to mix both lift & shift and re‑architecting. You can lift & shift now to avoid
delays. Then, re‑architect later in steps. This reduces risk. It also gives your team time to plan and learn.
This phased method helps manufacturers act fast but still build a better system over time.
