We are using Websphere Portal Server 126.96.36.199. There are many users that has been created in portal server. Now we are migrating from websphere portal server 188.8.131.52 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 184.108.40.206 to portal server 5.1. Is there any way to copy all the portal users.
