Welcome back to the Wefugees Community and thank you for reaching out to us again.
Your friend will need to submit a so-called "Umverteilungsantrag" to the local immigration office (Auslänerbehörde) and explain her reasons very well, why she wants to move to another place. During the pending asylum procedure, people are usually required to stay in the city to which they were initially transferred. Maybe she can consult a aslyum counselling office to get support in explaining her situation and the advantages of moving. I hope this helps and please don't hesitate to get back to us with any further questions.
All the best,
