The following two are additional steps for Switch-Over instance migration (for Runtime environment only). You will not need to do these before migrating a local WebSphere Commerce Suite V5.1 instance or a WebSphere Commerce Studio V5.1 instance.

1.Package WCIM on v5.6 machine and its environment for remote execution: Run WCIM to create a zip file including WCIM itself as well as the environment it requires. This package will be used to build the migration environment for the Switch-Over migration.

2.Unpack WCIM on v5.1 machine: Unzip the WCIM zip package generated above. This builds the runtime environment with correct level of JDK, XML parser, ANT, Configure Manager client, WCIM while maintaining the file permission and ownership. Note that since the package created includes all these platform dependent files, scripts and attributes you can not migrate across platforms.

Migrating a local WebSphere Commerce Suite V5.1 instance or a WebSphere Commerce Studio V5.1 instance:

1.Backup the instance to be migrated: Backup of the WebSphere Commerce runtime environment is required in case of Switch-Over instance migration. It is optional, but recommended, in other instances. The backup includes:

Configuration and installation information of the previous WebSphere Commerce install

The configuration information of the WebSphere Commerce instance to be migrated

The configuration information of the local IBM HTTP Server

The configuration information of WebSphere Commerce Payments and supported payment cassettes and the deployed EAR.

If there is no EAR, WCIM will collect enough information to be used to build a migrated EAR. All files are compressed into a single ZIP backup-instance.zip to be transferred to the target WebSphere Commerce server.

2.Migrate the instance: This includes:

Creating a migrated EAR based on the original EAR and the default EAR in the new release.

Stores published before migration are wrapped into a Web module. Multiple Web modules and resource adaptors are added.

EJBs for the correct database type, JSPs, servlets, commands, HTML files, images from the new version are packaged into the migrated EAR, too.

An application server 'WC_xxxx' is created with the correct configuration required to run the migrated EAR.
