Our “Migration” is based on investigating fact-basedly and executing consistently the migration process as Migration Planning – Migration Design – Resource Conversion – Testing.
While the legacy system is running, the migration is performed to stably base environments to minimize the influence on daily business.
Common tasks
The following issue can be optimized from our long-termed experience in company:
・High cost of maintenance
・Feebleminded power
・Dependence on platform
・Low business variability
・Insufficient cooperation with an open system
・Old version
・Lack of trained engineers


Our own developed migration tool
With years of various experience of migrating & operating the mainframe, we can migrate to new system without losing the convenience of old sytem and then develop a migration tool with the following important points:
・Lower maintenance cost
・Improvement of performance & quality
・Better target to business
・Integration to an open system
・Lower engineer’s dependence
