Migration services

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).

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.

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.
