Mechanisms for migration in a communication network of VNFs to VIMs. A method is performed by a migration controller. The method includes obtaining information of network complexity per VNF, information of VM usage per VNF, and information of processing capacity of compute nodes per VIM. The method further includes determining a mapping between the VNFs and the VIMs. The mapping defines at which of the VIMs each of the VNFs is instantiable. The method further includes ordering the VNFs in a list by matching the information of network complexity per VNF and the information of VM usage per VNF to the information of processing capacity of compute nodes per VIM and taking into account the mapping between the VNFs and the VIMs. The method further includes initiating migration of the VNFs to the VIMs in the order defined by the list.
