Claim 0:
1. A system to migrate a set of network functions between control planes of network slices, comprising:
a network slice A that comprises a first set of a plurality of network functions in a control plane associated with a legacy vendor;
a network slice B that comprises a second set of the plurality of network functions in the control plane associated with a new vendor wherein the second set of the plurality of network functions comprises a subset of the first set of the plurality of network functions in the control plane of network slice A; and
a migration management unit to manage a gradual staged transfer of a subset of the plurality of network functions originally contained in the control plane of the network slice A to the control plane of network slice B wherein the gradual staged transfer is a migration of the plurality of network functions in a set of multiple staged transfers to create the subset of the plurality of network functions in the control plane of network slice B, wherein:
each staged transfer comprises the migration of a reduced subset of the plurality of network functions contained in the control plane of the network slice A reconfigured to the control plane of the network slice B;
the network slice A is originally configured in a pre-migration setup that comprises a plurality of previously mapped network functions mapped to the control plane of network slice A wherein the network slice A comprises a set of a plurality of User Equipment (UE) profiles; and
the plurality of UE profiles are updated with the network slice B only after a first staged transfer of the set of multiple staged transfers and prior to any subsequent staged transfers.
