Hi Prathamesh Chavan,
You can export all the TP Identities using export script by defining the parameter as,
SCI_ENTITIES[1]=ALL
Please be aware that this will also export the Delivery Channels, Document Exchanges, Profiles, Transports, Packages and Entity Extension data (for SFG Partner Identity) referencing the identity getting exported.
