Data migration is one of the most prominent challenges organizations face during ERP implementation. The numbers suggest that about 83% of data migration projects exceeds their budget or deadlines. Data migration is one of the main reasons behind an unsuccessful Open Source ERP implementation. Fortunately, all these failures have taught some of the most valuable lessons about data migration to many. Therefore, to make this easier for everyone, here are a couple of tips that will help you drive seamless data migration and get the job done before reaching the deadline or exceeding the budget.
Amount Of Data: You need to determine the amount of data to be migrated. It is alright to take your time with this, but is very clear about the data sets that have to migrate to the new system. Migrating data from a legacy system to a new robust system can often result in amplified complexities, inefficiencies, and even expensive. Therefore, it is essential to ensure you take a deep look into the data and weed out the data sets that do not have to be migrated to the new system. This will help you reduce overall data migration expenses.
Building Data Dictionaries: Managing large data listings with data dictionaries can make things very easy when migrating to a new ERP system. Data dictionaries are a great way to ensure that the quality, meaning, and relevance of the data elements are the same for every stakeholder across varied departments and business users. This is also a great way to provide information to those responsible for building applications and systems that support data. Further, data dictionaries can help one simplify the data structure for the new system and get rid of all the data redundancies.
Ensure The Legacy System Is Running: This might sound ineffective, but in many cases keeping the legacy system as read-only can be very useful for organizations. Doing this until everything is moved from the legacy to the new system can help one ensure their solutions have the appropriate processes and functions for successful data migration. Experts recommend keeping the legacy system running for about six to eighteen months, depending on the time required to access the legacy transactional data.
Ongoing Or One-Time Migration: People often assume that migration is just a one-time process. However, that is not always the case because there are specific alternatives, as many businesses are now opting for ongoing migration. This way, one can leverage a flow of different changes from the legacy system to the new ERP. Feel free to do this after the initial full dump and load. There can even be scenarios where the legacy systems have to live for an extended period. In such cases, it is better to opt for ongoing data migration as it allows you to migrate data more accurately and promptly.
