The data migration phase of a modernization project introduces a thorny critical path.
Companies that have been around for decades, steadily collecting and storing data, have sizable volumes of data to work with, making the task complex and time-consuming.
The good news: with the right approach, data migration can be eliminated entirely.
Traditional Data Migration
Depending on the approach, traditional data migration projects can get mired in snags causing timelines and associated costs to explode.
The traditional approach, in general terms, is a three-step process: Extract the data, transform it to fit the new system, then load it. But on the way, you need to manage the complexities of data mapping, cleansing, and quality.
These task challenges can create endless stop/start cycles and push your deadlines into the void.
Bypass the Data Migration Process with Coexistence
So how do we skip this step entirely and avoid all the headaches?
A best-practice approach is to create a new system that works alongside the legacy system, eliminating the need to migrate the data entirely. This approach is called “coexistence.”
With coexistence, the new system is built to communicate with the legacy system in real-time. Data is accessed by the new system on an as-needed basis only.
Executed successfully, a coexistence approach can bypass the risks and costs associated with traditional data migration and put your modernization milestones closer to the here and now.
Coexistence can also be a boon to the information workers in your company. They can continue to work the way they have been long-trained on the legacy system and transition to the new feature set in a more low-stress, intuitive, and methodical way.
