Migration is a sysmodule designed for handling the Switch-to-Switch transfer system introduced in firmware 4.0.0.

With newer system-versions this sysmodule is only running when qlaunch is using migration from the relevant transfer menus (see ActivateMigrationService/DeactivateMigrationService).

mig:usr

This is "nn::migration::user::IService"

CreateUserMigrationServer

Takes a total of 0x18-bytes of input, a type-0x19 input buffer, a TransferMemory handle, returns an #IServer.

ResumeUserMigrationServer

Takes an input u32, a TransferMemory handle, returns an #IServer.

CreateUserMigrationClient

Takes an input u32, a type-0x19 input buffer, a TransferMemory handle, returns an #IClient.

ResumeUserMigrationClient

Takes an input u32, a TransferMemory handle, returns an #IClient.

GetSaveDataMigrationPolicyInfoAsync

Takes an ApplicationId, returns an #IAsyncSaveDataMigrationPolicyInfoContext.

This is used by qlaunch before the actual savedata transfer is started.

This starts a network request for save_data_migration_policy.

CreateSaveDataMigrationServer

Takes a total of 0x20-bytes of input, a type-0x19 input buffer, a TransferMemory handle, returns an IServer.

ResumeSaveDataMigrationServer

Takes an input u32, a TransferMemory handle, returns an IServer.

Cmd1110

Takes a total of 0x18-bytes of input, a type-0x19 input buffer, a type-0x5 input buffer containing an array of u64s, and a TransferMemory handle. Returns an IServer.

This is identical to CreateSaveDataMigrationServer except the u64-array is passed directly instead of from a single input u64.

CreateSaveDataMigrationClient

Takes an input u32, a type-0x19 input buffer, a TransferMemory handle, returns an IClient.

ResumeSaveDataMigrationClient

Takes an input u32, a TransferMemory handle, returns an IClient.
