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.

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
