Remedy Migrator architecture
Remedy Migrator integrates with Remedy AR System through existing application programming interfaces (APIs) and requires no additional integration work. You can install Remedy Migrator on a client workstation and run it independently of Remedy AR System. The APIs handle all communication between Remedy Migrator and Remedy AR System servers.
Remedy Migrator and Remedy AR System server integration
Remedy Migrator can transfer server objects across one or more servers and also transfer data entries from one or more Remedy AR System forms. You can select single, multiple, or searched sets of data. You can migrate data immediately or save your migration in a script to be run later.
