Portal, Express Beta Version 6.1 Operating systems: i5/OS, Linux,Windows

Planning for migration

Each migration is unique, depending on the earlier version of IBM^® WebSphere^® Portal Express that you are migrating from. Successful migration requires careful planning and execution, understanding the hardware and software requirements, and being aware of the tools, techniques, and issues that are involved.

You can migrate information to WebSphere Portal Express Version 6.1 from these earlier offerings:

• IBM WebSphere Portal Express Express Version 5.0.2.2, 5.0.2.3, and 6.0 or later
• IBM WebSphere Portal Express Express Plus Version 5.0.2.2 and 5.0.2.3

Throughout the rest of the migration topics, all WebSphere Portal Express versions prior to Version 6.1 are collectively referred to as the previous version and Version 6.1 is referred to as the current version.

Before you begin

Hardware and software requirements vary with each WebSphere Portal Express version. Before migrating, determine whether you need to upgrade your operating system. For example, if you want to migrate data from V5.0.2.2 running on Windows^® 2000 Server, you need to upgrade your operating system to Windows 2003.

You can migrate from an older version of an operating system to a newer supported version of that operating system Migrating between different operating systems, however, is not supported. For example, you cannot migrate from a Windows operating system to a Linux operating system.

When installing to Linux, ensure that the ulimit for your operating system is set to 10240.

WebSphere Portal Express migration reuses the database tables from the earlier version in the current version.

You can migrate from an older version of a database server to a newer version of that database server. Migrating between different database servers, however, is not supported. For example, you cannot migrate from a DB2^® database server to an Oracle database server.
