Update bp.conf from masters server

We are doing a migration about 100+ clients daily. these all are Linux client. this migration to new DC so new master and media server but clien name is same.

so in that case we have to update bp.conf manually in all clients (remove old master/media server name and add new master/media). is there any command/script by this we can update client bp.conf from master server without doing login on client.

Master server is Windows 2008 and NB version is 7.5.0.6.

Client- Linux Redhat
