- Call dmi–plugin rest endpoint to retrieve all modules on new node (depends
CPS-483andCPS-531) - Call CPS-Core rest endpoint to get all existing modules in cps-core (depends CPS-506)
- Calculate difference (delta)
- Call dmi–plugin rest endpoint to retrieve missing modules
CPS-483 - Add missing modules to cps-core to anchor (cm handle) (depends CPS-508)
Implementation Proposal
Within the DMI plugin there is a method where cm handles are sent to a registration method in NCMP.
From: DmiServiceImpl.registerCmHandlesWithNcmp(final String jsonData) To: NetworkCmProxyController.updateDmiPluginRegistration()

Append deriving modules after line 137 in method updateDmiPluginRegistration() in NetworkCmProxyDataServiceImpl
deriveModulesForCmHandle(cmHandleJsonData);
get cm handles from string
call dmi to get modules for this cmhandle
compare with cps and get delta
call dmi for delta modules
