We are using Websphere Portal Server 184.108.40.206. There are many users that has been created in portal server. Now we are migrating from websphere portal server 220.127.116.11 to 5.1(Basically we are re installing the portal server). We need to migrate all the users that has been created in Portal Server 18.104.22.168 to portal server 5.1. Is there any way to copy all the portal users.
