Draft Document for Review July 28, 2004 7:33 pm 6320ch_migrating.fm
For more information on instance migration approaches please refer to
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.
11.2.1 Migrating the instance
This section describe the tasks needed to migrate an WebSphere Commerce
instance.
Note: Although Co-existence is supported by the WCIM tool, it is not
supported in Microsoft Windows platform.
