WebSphere® Application Server Versions 5 and 6.0.x support foreign cell bindings, but support is limited to a single bootstrap address and you cannot configure foreign cell bindings in the console. The single bootstrap address used in Versions 5.x and 6.0.x has been deprecated, replaced in Version 6.1 and later by a list of bootstrap addresses.
This topic describes how to migrate any Version 5.x or 6.0.x bootstrap addresses to use Version 6.1 or later foreign cell bindings. Version 6.1 and later foreign cell bindings enable you to specify more than one bootstrap address and enhance failover support.
Nodes running at a version later than Version 6.0.x ignore the old single bootstrap address setting in preference for the bootstrap address list. If the convertScriptCompatibility command encounters a foreign cell binding configuration with the old single bootstrap address and the newer bootstrap address list both set, the old single bootstrap address is removed and the bootstrap address list is left unchanged.
Console foreign cell binding panels in Version 6.1 and later only display and update the bootstrap address list. They do not change the single bootstrap address configuration setting. If you use the console to edit a foreign cell binding configuration that existed when the cell was initially migrated, and you have not yet run the convertScriptCompatibility command, the updated binding configuration contains both the original single bootstrap address and whatever list of bootstrap addresses you configure in the console. In the migrated cell, nodes still running at Version 5.x or 6.0.x continue to use the single bootstrap address configuration setting to bind foreign cell bindings in the namespace.
