The migration requires installation of required Portal and WebSphere binary installations. Before starting the migration, apply the latest cumulative fix and the most recent fix. In addition, create new copies of the source databases for the target environment to use, and prepare the target environment for any custom applications with dependencies or any other tasks that need to be performed for remote or cluster migrations.

Prerequisites

WebSphere Portal detailed system requirements

The target environment can be one of the following environments:

• A separate system
• A remote migration
• The same system (local migration path)

Independently from the migration path chosen, the target environment requires a fresh, binary only, Portal installation. Meaning setting up the target environment without creating any profiles.

1. Roadmaps for migration
2. Target environment considerations
3. Install Portal and WebSphere binary files
4. Install fix packs on the target environment
5. Copy portal binary files to the deployment manager
6. Copy files for third party and custom applications
7. Target environment: Maximum open file descriptors for Unix-based platforms
8. Use copies of source database domains to minimize downtime
9. Database considerations
