Preserving a Version 5.1 gateway when migrating a cell

When you migrate a cell to a later version, any previously configured gateway on any Version 5.1 application server in the cell is replaced with an empty gateway. Therefore you must preserve your Version 5.1 gateway configurations before you migrate the cell.

Before you begin

WebSphere® Application Server Version 5.0 is no longer supported, so you should migrate any existing gateways that are running in Version 5.0 application servers to run on application servers at the current level of the product.

Before you choose whether to preserve or migrate your Version 5.1 gateways, you should be aware of the context and restrictions that are described in Coexistence: Preserve or migrate a Version 5.1 gateway.

To migrate a gateway, see Migrating a Version 5.1 Web services gateway configuration.

About this task

Because a cell in a later version can contain application servers at different versions, you can continue to use Version 5.1 gateways that are running on Version 5.1 application servers even if you migrate the cell from Version 5.1 or Version 6 to Version 7.0. However when you migrate a cell, any previously configured gateway on any Version 5.1 application server in the cell is replaced with an empty gateway. Therefore you must preserve your Version 5.1 gateway configurations before you migrate the cell.

To preserve Version 5.1 gateways and application servers when migrating a cell to a later version, complete the following steps. For information about how to save and restore the Version 5.1 gateway configurations, see the WebSphere Application Server Version 5.1 topic: Backing up and restoring a gateway configuration.

Procedure

  1. Save the Version 5.1 gateway configurations.
  2. Migrate the cell to the later version without also migrating the application servers, by referring to the documentation about migrating deployment managers.
  3. Restore the Version 5.1 gateway configurations to the Version 5.1 application servers within the cell on the later version.
