Savedata transfer ("nn::migration::savedata::IServer"/"nn::migration::savedata::IClient") requires that accounts are linked to the same network-account. acc:su [[NS_services#IManagerForSystemService|IManagerForSystemService]] GetAccountId is used here. The server stores this Id into state, and also stores it in the [[LDN_services|ldn]] AdvertiseData. The client also verifies the Id in AdvertiseData against the Id from GetAccountId for the account(s) being used, during ScanServersAsync.

[S2] [[qlaunch]] now has an additional menu once send-savedata is selected, for selecting whether to send to Nintendo Switch or Nintendo Switch 2. If Switch 2 is selected, and there's a S1 receiving, the S2 will display a message regarding wrong target system. The receiving system also displays an error. Note that savedata for S2-only applications is only listed with the dest-S2 option (S1-applications are also listed).
