Legacy System Upgrade: 7 Migration Challenges to Consider

Migrating legacy software is akin to constructing a house of cards. One false move–whether it’s due to poorly defined processes, unskilled users, rigid workers adhering to outdated workflows, or financial constraints–and the entire system is derailed.

As a result, most businesses are hesitant to migrate from their old software or legacy system and leave their comfort zones. However, success and growth can only be found outside of one’s comfort zone. Thus, in order to be relevant in the market, you must constantly innovate, change, and push your boundaries. It is critical that you understand that what was useful a few years ago may no longer be the case. It is preferable to embrace change and migrate.

Isn’t it frightful?

The good news is that with careful planning, timing, and, most crucially, budgeting, you can ensure a smooth transition to the new system.

The article will familiarise you with the obstacles of software migration and how to deal with them, allowing you to minimise the risks associated with it. But first, let’s go over the reasons why you should move your software.

What is the need to migrate your legacy software?

Every software product, no matter how complex, expensive, or cutting-edge, has a limited lifespan. Every system that supports your organisation will become obsolete in the long term, either due to new developments leaving the technology obsolete or due to the changing needs of the firm. Existing software will eventually need to be upgraded or replaced by moving to a new system.

Here are some possible reasons for migrating from the legacy system.

  1. It provides an advantage in the marketplace.
  2. To increase the system’s efficiency.
  3. If the expense of maintaining and licencing your current system is prohibitively expensive.
  4. Legacy software is not adequately safeguarded.
  5. If the legacy software is inefficient.
  6. If there are compatibility concerns with the software.
  7. If technology advances

Legacy System Upgrade: 7 Migration Challenges to Consider 2

Change usually costs something; it could be time, money, comfort, or all of the above. Adapting to these changes is a significant challenge. When it comes to software migration, one of the most significant changes for a company, it also brings with it the following challenges:

Challenge 1: Mapping out an Effective Plan

If you are not someone who believes in planning, software migration will be difficult for you. Failing to plan, according to Benjamin Franklin (an American polymath), is the same as preparing to fail. This is also true for software migration.

Several procedures must be completed prior to the migration of legacy software to a new software or cloud solution. Along with establishing the system, you must train staff, maintain it, and set up a support system. Planning can be really beneficial in this situation. Planning allows you to manage things more successfully and avoid problems down the road.

Challenge 2: Budget

The budget involved with the migration process may be the most difficult barrier you face while converting your legacy system. Calculate the total cost of the migrating procedure and compare it to your estimated budget.

If your budget allows it, begin the relocation procedure. Among the costs to consider during the procedure are:

  1. The expense of the cloud or software to which you are migrating.
  2. The expense of implementation.
  3. The cost of hardware upgrades, if necessary.
  4. Employee training costs money.

The cost calculation will also assist you in estimating the return on investment of the relocation procedure. This will tell you whether or not it is profitable to move the programme. You can plan your migration based on this.

Challenges 3: Data Migration

Data is an organization’s most valuable and vulnerable asset. The loss of a single record can have major consequences for their reputation and work. As a result, before proceeding with the conversion, ensure that you have prepared a detailed plan for migration and data backup in your legacy programme.

It is highly suggested to map every data field from one system to another to ensure that the data has been effectively migrated and without loss. Mapping not only makes your data migration fault-proof, but it also allows you to assess its accuracy and efficiency. In addition, there are a number of solutions available to help you avoid data loss.

Challenge 4: Post Migration Preparation

The obstacles do not end with the relocation procedure; certain risks and challenges can emerge after migration as well. Even if you meticulously implement the migration procedure, there is still a potential that the transferred system will fail. Make certain that the procedure does not begin in the first place.

You should have a contingency mapping and backup or continuity strategy in place for this. This will not only help you avoid future blunders, but it will also help you fix any issues that arise after the migration. Here is a post-migration checklist for you to consider:

Here is a post-migration checklist for you to consider:

  1. Examine the migrated data.
  2. Examine the support channels for both the old and new software.
  3. Examine the knowledge base linkages.
  4. Check that the templates are up to date.
  5. Check that the integrations are properly configured.
  6. Increase user awareness about software migration.
  7. Ensure that the testing procedure is followed correctly.

Challenge 5: Dependency Bottlenecks

You should identify the indirect dependencies in addition to the direct dependencies, which are the software, hardware, and users who are directly affected by the software. Users, software, and hardware that are indirectly linked to legacy software are referred to as indirect dependencies.

Make sure you understand all of the system’s interdependencies and make the required arrangements. To determine the dependencies, momentarily shut down the software and then, if any notifications are received, list the dependencies. As a result, when migrating the programme, you will be able to make the appropriate adjustments for the dependant software.

Failure to recognise interdependencies can lengthen migration timeframes and raise expenses. It is critical that you verify that migration timelines are acceptable.


Software migration is also a component of your company’s progress. So, after you’ve decided to move away from legacy system software, it’s a good idea to think about the above issues before starting the process to make the transition go more smoothly.
