how to migrate back data source to BW3.x from BI7.0

Dear Gurus,

In our development system one of our colleague migrated the MM data sources from 3.x to 7.0. When we create transfer rules, at data source assignment I cannot see these data sources in the list. Please help me to convert back to BW3.x from BI7.0 for these data sources. Do we have this flexibility?

Thanks

Ram
