Migration overview

Migration is the process of collecting configuration data and applications from an earlier installed version of IBM WebSphere Portal and merging them into a newer installed version. So the new environment is identical to the earlier environment.

Migration is different from upgrading. With upgrading, you replace an existing installed out-of-date version of files with current files. With migration, we install the new version of a product alongside of the earlier version and then copy data from the earlier version to the new version. By migrating information from the earlier version to the new version, use that information in the new version without having to re-create it from scratch. Migration enables customizations to be carried forward that were implemented in the earlier portal so we can continue to use them in the new portal.

WebSphere Portal also supports integration with additional products to extend core functionality. If the earlier portal environment is configured to work with one or more supported products that provided integrated features, we need to follow the migration procedures for the integrated product.

Migrated elements are not automatically upgraded to use features available in the new version. Taking advantage of new features that were not available in the earlier portal requires extra attention after migration is complete.

We can migrate to WebSphere Portal v8.5 from either v7.0.0.x or 8.0.0.x. See Supported migration paths

If we are migrating from IBM WebSphere Portal v8.0.0.1 on WebSphere Application Server v8.5.5.2 to WebSphere Portal v8.5, follow a different migration process. See Migrate from Portal 8.0.0.1 on WebSphere Application Server 8.5.5.2

Migration to v8.5

For v8.5, data, applications, databases, property files, security settings, and configuration are migrated using the Configuration Wizard. Use the roadmaps for cluster and stand-alone migrations to guide you through planning, preparing the source environment, setting up the target environment, migrating data, and post-migration steps. See Roadmaps for migration.
