Support for investigation, modification, and migration of business systems due to the end of OS support.
J&C Company, Inc.
Is it okay to just update the OS? We compared five options, including investigating the business system, database, and peripheral devices, as well as partial modifications and migrations. We have published a document with a response plan sheet.
"Support for the OS has ended," "We cannot update due to an old business system," "We do not know if it will work in the new environment" — J&C supports the investigation, modification, and migration of such existing systems. When updating the OS, it is important to check the impact not only on the business system but also on the database, middleware, external integrations, and peripheral devices. First, we investigate the current configuration and operating environment. Based on the results, we compare OS updates, partial modifications, temporary measures and migration preparations, web-based solutions, cloud migration, and replacements. We consider the future usage period and the impact on business to determine the appropriate response. The published material "Know-how Collection for Business System Response to OS Support End" is A4, 4 pages long. It explains six points to check, five options, four stages of migration procedures, and testing and recovery verification. A response planning sheet that can be used in-house is also included. You can consult us even if there is no specification document or if the response policy has not been decided yet. The feasibility and scope of the response will be determined based on the current situation investigation.
