Chapter 3, “Migration Strategy and Planning” on page 37

We choose to do an Switch-Over migration as we had available hardware running WebSphere Commerce V5.6.

The following are the high level steps that needs to be performed during a Switch-Over migration:

1.On your WebSphere Commerce V5.6 system, create a package that contain all files needed to execute the WCIM tool on WebSphere Commerce Suite V5.1 system.

2.Transfer the package from your WebSphere Commerce V5.6 system to your WebSphere Commerce Suite V5.1 system.

3.Extract the package on WebSphere Commerce Suite V5.1 system.

4.On your WebSphere Commerce Suite V5.1 system, backup your current WebSphere Commerce instance and the instance-related assets using WCIM.

5.Transfer the instance backup produced by WCIM from WebSphere Commerce Suite V5.1 system to your target WebSphere Commerce V5.6 system.

6.Migrate instance using WCIM.

7.Verify that the instance was migrated successfully.

The steps must be repeated on each instance, if more than one instance is to be migrated.

During the steps performed on WebSphere Commerce Suite V5.1 the server does not need to be shut down, but it is recommended to shut it down or do it at a time when there is minimal load on the server.

The migration script WCIM, does not need the WebSphere Commerce V5.6 server running.
