Although TPM-2 is now cleared for use with the DDS changing over to the new missile will be a gradual process as ships will require modifications to their missile handling systems, launchers and tactical systems. The number of ships able to operate TPM-2 is increasing however and now the entire Quasar fleet (except Tachyon which is still in refit) is now operating TPM-2 as the type's ILU this year added that capability.
The Pulsar MULE3 and Panther fleets are also operating the missile though until the frigate fleet receives the changes required the TPM-1 will remain the most common weapon in the DDS arsenal. The Isometric ILU which will begin next year however will include TPM-2 support and the Terran Sea fleet will have it also next year when it undergoes it's Terran Sea Enhanced Capability Update 2109. It is thought by mid-2110 the majority of ships in the fleet will have TPM-2 support though the DDS do not expect to change every single ship over until 2115 or 6 (though as even Starsystems have TPM-2 support already that date may be overly pessimistic).
