The following is a general ordered list of tasks that are required to complete an In-place migration:

Take WebSphere Commerce Suite V5.1 production server offline Backup production system

Perform pre-migration actions

Install (for coexistence) or update software levels to WebSphere Commerce V5.6

Perform instance migration Migrate database

Deploy migrated code from the development machine Complete required migration tasks on the test server Test migrated instance

Bring WebSphere Commerce V5.6 test server online to become the new production server

3.6 Approach used for this migration

In our approach our main goal was to minimize the downtime of the production server. To achieve this we chosen the Switch-Over migration.

Our final production environment consisted of a three nodes - a WebSphere Commerce node with a remote database node and a remote WebSphere Commerce Payments node. Initially, however, we migrated the WebSphere Commerce and database to a single node. Then, once we had successfully tested the migrated environment and we were satisfied with migration to WebSphere Commerce V5.6, we moved the database to a remote database server creating a three node environment as the original system topology.

While we were migrating the solution, the first stage of the migration, the WebSphere Commerce Suite V5.1 remained running thus we had minimal downtime. As soon as we had migrated we switched over the actual production environment from WebSphere Commerce Suite V5.1 to WebSphere Commerce V5.6, WebSphere Commerce Suite V5.1 remained operational as our backup incase of problems.

Below are described the high level tasks we performed to do a complete migration on the development and runtime. It is important to migrate the development environment first so that you have the migrated code for deployment after you have migrated the production environment:

1.Migrate development environment

2.Migrate production environment
