Change network address of rhevm network

Hello.

Each rhev-h has two bonds: bond0 is rhev-m and bond1 is VMs logical network. My customer needs to readdress rhevm network. They need to do it online, that is they would like to have the VMs working during readdressing (VMs are not to be migrated).

Is it possible to do it online ?

Could anyone provide some procedure describing how to do it ?
