Overview of migrating policy sets and bindings

Policy sets are migrated during the product migration from Version 6.1 Feature Pack for Web Services or Version 7.0 to Version 8.0. The different rules that apply to migrating policy sets and bindings are described. For information about migrating the version of the product that you are running, see migrating and coexisting.


Migration from Version 6.1 Feature Pack for Web Services

Migration rules for policy sets

For the following policy sets, the migration code first checks for any application attachment for a policy set. If there is an application attachment, the migration code upgrades and renames the policy set to oldPolicySet_wsfep; then updates the policy set attachments from oldPolicySet to oldPolicySet_wsfep in Version 7.0 and later. If there is no attachment for the policy set, then the policy set is not migrated or renamed.

Other policy sets are migrated to Version 7.0 and later only if there is no other policy set in Version 7.0 and later with the same name.

Migration rules for bindings

In Version 7.0 and later, custom bindings are called application specific bindings. Read web services policy set bindings.

The following migration rules apply to application specific bindings, cell level default bindings, server level default bindings, and trust service bindings:

Application specific bindings

During migration, the Version 6.1 application specific bindings in the applications are not upgraded. They are copied with the applications to the Version 7.0 and later system. After migration, we can upgrade the Version 6.1 application specific bindings in an application using the administrative command, upgradeBindings.

Cell level default bindings

During migration, the cell level default bindings from the Version 6.1 Feature Pack for Web Services are copied to the Version 7.0 and later system, and they replace any existing Version 6.1 cell default bindings in the Version 7.0 and later system. The Version 6.1 cell default bindings are migrated to general bindings in Version 7.0 and later.

There is a security fix for the Version 6.1 cell level default WSSecurity bindings. Run the script, updateBindings.py located in WAS_HOME/bin to fix issues with the Version 6.1 cell level default WSSecurity bindings.

We can install a WAS v6.1 Feature Pack for Web Services application within the WAS v7 and later environment. If the application contains Version 6.1 application specific bindings, the application is defined as a Version 6.1 application to the application server. Additionally, if the application is installed on a WAS v6.1 Feature Pack for Web Services server within the WAS v7 and later environment, the application specific binding is created as a Version 6.1 application specific binding.

When creating an application specific binding, the system checks to see if the application is installed on a Version 6.1 server or if the application contains any Version 6.1 application specific bindings. If either of these conditions is true, the system creates Version 6.1 application specific bindings. In addition, you are not allowed to assign a general binding to a policy set attachment for that application because general bindings are for Version 7.0 and later level of the product.

Server level default bindings

During migration, the server default bindings in the Version 6.1 Feature Pack for Web Services are copied over to the Version 7.0 and later server. The server default bindings are also migrated to general bindings. We can decide whether or not to use these general bindings as the Version 7.0 and later server default bindings. The Version 6.1 applications and other applications that are installed on a Version 6.1 server use the Version 6.1 default bindings.

Trust service bindings

  • Trust service bindings are migrated during the product migration. The migrated trust service bindings replace the trust service bindings in Version 7.0 and later.


    • Migrate general bindings from Version 7.0 and later to Version 8.0

    A general binding is migrated from Version 7.0 to Version 8.0 only if there is no other general binding in Version 8.0 with the same name. If a general binding is not migrated because it has the same name as a Version 8.0 binding, then we can export the binding from the Version 7.0 system and import it into Version 8.0 with a different name.

    The default binding settings which specify which provider and client bindings are used as defaults are not migrated from Version 7.0 to Version 8.0. We must modify your default binding settings in Version 8.0 to use the same defaults that were specified in Version 7.0.
