摘要：Problem statement: Software Reengineering is an effective technique for reuse the older application in the new environment. Nowadays, Reengineering techniques are increasing in spite of many difficulties and issues arise when the older application is converted to newer one. So there is a need to enhance the new system to satisfy the user requirements and quality aspects. Approach: For this enhancement of new system, we propose a method namely Automatic Specification Evaluator (ASE) where the interference and their effects on the new system were identified by their attributes and modify the interference if necessary. The accuracy of the migration was further increased by reimplementation of the same method. Results: After the proposed ASE method, the system interference was reduced and the efficiency of the new system was improved. In many migration situations, ASE produces the target system with zero interference. Conclusion: Our proposed method gives a good performance in the new system and hence the new system can adopt the properties of the legacy system and also satisfies the user requirements.
