Application migration can be very difficult in the case of enterprise software. But with the right implementations and features, you will be able to make it work very well. The question is, what strategies are better and how can you avoid any downfalls? There are a few ideas and topics that you may need to take into consideration.
Rehosting
One of the most interesting strategies relies on rehosting. The idea here is that you move from on-premise to the cloud. Doing that will not require major changes to the configuration and code. It will also help you save time and even remove potential data storage and hosting risks due to the cloud.
Retiring
The strategy will work in case you want to switch to a newer system and not rely on the older one anymore. With that being said, retiring some of the older infrastructure can be great if you want to free up resources. It also does an excellent job when it comes to reducing some of the maintenance costs, something you have to keep in mind. Retiring can be essential in the case of a cloud alternative.
Repurchasing
If you check the strategies, you will notice repurchasing is a very common one. The focus is on replacing those on-premise applications with a cloud-based alternative. It’s an option if you want to save money and time. However, the downside is that it can lead to major business changes. Plus, you will need to pick specific vendors, and you will lock into certain offers. While helpful, repurchasing can become restrictive, so that’s important to consider.
Refactoring
Refactoring can be complicated and expensive. As the name states, the idea here is that you are working with the existing code and you have to change it. In some cases, changing the code is very difficult, and you might even have to rebuild everything. It does provide better compatibility in the long term, but that also means you will have more expenses.
Replatforming
Replatforming is similar to refactoring, but you only make some changes to ensure that you get a cloud-friendly result. In most cases, you change the database and some features, but you will have a cloud-efficient system that can be expanded upon. It’s not a system that’s faster than rehosting, but it can help streamline and futureproof your software.
Picking the right migration strategy
There are multiple things to keep in mind when you choose application migration strategies. Interoperability and cooperation are mandatory in most cases. You also want to think about the cost of operation as well.
And there are other factors like security and compliance, all of which have become mandatory in recent years. And yes, you need to consider future-readiness and how your current strategy will impact any changes. All of these ideas are imperative if you want to migrate your software and pick the best solution that will not bring any issues for your business. Consider all the ideas shown above and pick what’s suitable for your own company!
