Undergoing System Upgrades? Keep 5 Things in Mind

Without system upgrades, you cannot rival in this competitive world. Several are migrating their legacy applications to their new digital setups or completely doing away with them. Most are still using legacy infrastructure even though their vendors have long stopped providing support. However, any obsolete app you use is like a car. The longer you use it, the costlier it will be to maintain and upgrade. In this article at InfoQ, Vlad Vahromovs shares the factors to keep in mind when you are implementing system upgrades.

System Upgrades for Legacy

What Defines a Legacy System?

When you are making system upgrades to modernize legacy applications, the cost is 3x more than getting a new setup. So, you must analyze where to spend your budget. The author explains, “Legacy software is the product that no longer meets current business needs.” If any of the following features describe your system, it is a legacy application:

Incompatible with new development structure and systemsNot supported by the developing companyFit for an older infrastructure or applicationFixed several times due to frequent changes in development teamsScarce maintenance team availabilityComplicated to scale up because of its old frameworkNot integrable with several systems and faces several compliance challenges

Costs of Legacy System Upgrades

It might appear that you are saving money by delaying or preventing system upgrades. However, in the long run, you will pay more to get everything on track again. A recent study indicates that a US public authority shells out running and maintenance costs of $337 million every year for 10 of its legacy setups. Additionally, a regular company pays an incremental cost of 20 percent for support per year for the legacy upkeep.

What Are the Hidden Expenditures?

IT departments spend most of their time finding and fixing bugs in legacy applications.Since legacy setups do not have a suitable data backup module, companies must keep aside a hefty amount just to rearrange legacy databases.The newer software can handle data security challenges better than the older frameworks.Legacy systems face frequent breakdowns, and that can cause productivity downtime during crucial service hours.Vestd founder and CEO Ifty Nasir says, “businesses and customer types evolve so being hamstrung by an old system can make or break your success.”You miss taking on new projects since your legacy apps cannot support newer development requirements.

What to Remember During System Upgrades

Figure out what a modern system should be like and then make plans accordingly.Research if you actually need the change now or a couple of years later will be fine.Do not stick to just a single strategy for system upgrades. Customize your transformation approach. Determine whether you must replatform, reface, rebuild, or extend or migrate.When you are migrating or building a new setup, you must take care of the data, be it archived or current.Have a thorough documentation process.Not only legacy apps but people will also resist new system upgrades. You must conduct training and meetings to help them realize the benefits.System upgrades take months to complete. Chalk out hours and processes that you can update with minimal discrepancy.
