Migrating the Payments application
Select an appropriate migration path depending on the machine topology.
- Migrate Payments application using one machine
This type of migration will have both the previous version of WebSphere Commerce Payments and WebSphere Commerce Payments, v7.0 running on the same machine. For example, if you have a previous version of Payments application, then you can migrate the application to WebSphere Commerce, v7.0 Payments level on the same machine and use it. Whether both the original application and the migrated application can run concurrently on the same machine depends on if they use same database and Web server port number.
- Migrate Payments application using two machines
This migration migrates the current version of the Payments application (which is installed on one machine) to the WebSphere Commerce Payments v7.0 (which is installed on a different machine). After migration, the migrated Payments instance on the WebSphere Commerce Payments v7.0 machine and the original Payments instance can continue to function. For example, if you have a previous version of Payments application, you can migrate the application to WebSphere Commerce Payments v7.0 on another machine. The migration allows both the original application and the migrated application to run concurrently on the two machines.
