In other words, this is actually extremely necessary in today's large and large environment where science and technology are developing rapidly. So-called, simply put, is some ages a bit old? The old system program is like this. Maybe in the past, this system was quite powerful, powerful and good. But now technology waves are coming one after another, and its problems and limitations that have worked so well in the past have gradually emerged. For example, the running speed is getting worse and worse, and it is becoming more and more difficult to maintain.
Then let's talk about what needs to be done
First of all, it is very important to understand the current status of the heritage system. You have to figure out which aspects of the old system are still well used and which ones need to be overhauled. We have to take a comprehensive and detailed look at its functional aspects, stability level, and compatibility with other new systems, and we have to see what the data is. Otherwise, it would be worse if you do something randomly afterwards. There will be a lot of trouble, delay work progress, and cause a lot of waste. For example, if an old-fashioned bank account record system was not examined in its comprehensive interaction and storage capabilities with today's new payment and transaction systems, then there is no way to discuss updates and improvements.
Another point is to determine the reasonable upgrade or replacement route. Should you want to upgrade or transform it on the original basis, or simply create a brand new modern system to replace it? You have to think carefully! Upgrading is sometimes a smart and economical approach. It only replaces some old components in the original architecture, such as applying a new programming protocol interface. If the original business logic does not change much, you can replace some old program blocks with the new version of the code, so that the system can run more efficiently and steadily improve performance, but the functions also need to be re-planned and designed. If it is replaced, it is often impossible to consider more when the old system is basically in line with the current situation. Use a new system to completely create a new system with more advanced framework language to replace the old heritage. For example, in the past, medical institutions simply manually enter patient information data and case methods, now they will be replaced by a new digital cloud-based medical record and case storage and retrieval system.
There are many things to pay attention to when I come here again:
1. After this upgrade, you must deal with the work together with the existing system. Just like after upgrading the original order management system in the enterprise, you must consider the operation and connection process of other different business functional systems related to material supply, cargo warehousing, etc. After upgrading, you must not always have no problem here but make other businesses messy and interrupt the chain.
2. For upgrading or transformation, the corresponding tests must be done in advance for data rules that involve the use of various new technologies or changes. First, small sampling tests should be carried out to ensure the correctness and accuracy of the data. Also, ensure that the system will not be affected by these changes.
3. If you choose new technology to improve or directly create the old system to replace the original, you have to estimate and consider the cost of learning and use properly. Employee training to learn this new thing at least requires time and funding. Otherwise, the effect of the new technology will really not be able to play any role. For example, the office used handwritten documents to record office work suddenly and used computer software. Many employees had never used office software before. They must be taught and used. They have to give a certain amount of time to learn and adapt to the use. Otherwise, the efficiency of the new method is not as efficient as the old method and it will delay work!
Of course, some friends must think about it. So what are the specific operational aspects of this process? This involves some details. Some people ask how to do data migration. This is a big problem. During the migration, precise plans and strict implementation procedures must be formulated. After carefully cleaning the data in the old system, carefully activate it within the newly built platform according to the standard corresponding methods. If it is not particularly rigorous, some dirty data will be caused in the process of data or application links. For example, how to coordinate the business department and the development team to cooperate efficiently. This matter must be handled well. Because the business unit knows what new requirements the technical team needs to understand how to effectively and correctly implement it. If the two helpers’ work communication is not smooth, it will delay the progress. If the progress is not fast, it will also be repeated changes to increase the development cost, etc.
Under the current situation, modernization of the old is indeed too critical. Nowadays, information technology is changing with each passing day. Only by keeping the system up to date can the system continue to stand firm in its respective fields and provide global procurement services for weak current intelligent products! Sometimes the newly developed system may require some material supply such as weak current equipment to help solve various digital problems. Habet can get stuck at critical moments and no material support. For enterprises and institutions to various organizations in scientific research institutes, we can plan and start this upgrade or replacement practice to face various situations more smoothly and effectively! It is indeed better to implement it early than to drag and procrastinate until you get old and never have a chance to turn things around.
