Hi Abdullah,
you can try to use Deployer to deploy the TN Assets from IS1 to IS2.
MWS is just a UI for the TN Server hosted on IntegrationServer.
Additionally make sure that you have applied the matching set of Fixes for TradingNetworks Server (TNS_) and TradingNetworks UI (TN_MWS_) on both instances. See Readmes of these for further informations.
Regards,
Holger
