With constant changes in technology, organizations today face many challenges from outdated IT systems. In an effort to maximize profits and stay ahead of the competition, many organizations are embracing and investing in legacy migrations.
Although many organizations want to invest in legacy migrations to update their clunky heritage applications and systems, they are not always quite sure where to start. For successfully implementing a migration, it is essential for you to understand the types of migrations needed and then choose a process which fits best with your organizational requirements.
Straight migration can be carried off without any complexity. Your current legacy system will be moved onto a new one without any upgrades what so ever. For example moving a filing system onto an MS excel sheet. This system is usually adopted by organizations that are perfectly satisfied with their current system, but want a slight increase in efficiency and performance. This method is pretty straight forward and can easily be handled by an in house IT team.
Legacy Migration with Extension
Even though an organization satisfied with their current system might opt for this type of a migration, the existing system might not be able to accept a new upgrade. For example, going from Windows XP to Windows 7 would not work efficiently on a system with 512 MB of RAM. If a situation arises, you would need to upgrade your current systems to incorporate 2GB of RAM or higher to ensure that all the migrations processes work smoothly.
Legacy Migration with Upgrades
This method is the most complex. All the features of the current system are moved into a new one and new functionalities are added. The existing features are renewed to enhance the efficiency of the current systems. This process can be complicated and it is best if you hire professional legacy migration service providers.
Before actually performing a legacy migration it is important to consider other aspects such as:
Considering all these factors and their impact on the end timeline is incredibly important. Before actually implementing the new system properly identify end users and take their opinion into consideration and communicate all expectations to the legacy migration service provider.
After successful completion of a legacy migration, there will be no gaps in your technology and you should seamlessly be able to drive productivity for business processes. Through rejuvenation of existing business systems, legacy migrations offer opportunity to embrace the technological change required for business success.
