move dc from old track to new track with different Track and vendor names

Hi,

we have a requirement where we need to move the 20 DC's  from a Track A with 7.1 components to a Track B with 7.4 components. Both the tracks are in the same SLD which is on 7.1. I have searched the SCN but could not find the thread, wiki which can help me.We tried to use DC Tool but no luck my server crashes after some time.Both the tracks had  different Software Components , track name and vendor name. We don't want to change the actual DC name.

Please suggest a solution.

Thanks
