uploading data from a third data processing device to the first data processing device;

subsequently replacing the third data processing device with the second data processing device; and

subsequently performing the providing steps.

2. The method according to claim 1, comprising

providing an uploading process configured for uploading of data from the third data processing device to the first data processing device;

providing an uploading information file for the uploading of the data from the third data processing device, the uploading information file containing at least one upload parameter for indicating a source portion in the third data processing device containing the data from the third data processing device to be uploaded; and

providing the uploading information file as an input to the uploading process.

3. The method according to claim 2, wherein

the uploading information file includes as the at least one upload parameter the at least one download parameter of the loader data file.

4. The method according to claim 2, wherein

the uploading process is configured to form at least one other loader data file as a result of the uploading process, and

the other loader data file is configured to be used as an input to the downloading process for downloading of data from the first data processing device.

5. A data processing device adapted for communications between the data processing device and a second device that comprises a control device of a people conveyor system controlling at least part of a function of the people conveyor system, comprising:

means for performing data transfer to the second data processing device; and

processing means arranged for

providing a download process configured for downloading of data from the data processing device to the second data processing device via a connection between the data processing device and the second data processing device,

providing at least one download parameter for the downloading of the data, the at least one download parameter containing information for indicating a downloading destination in a memory portion of the second data processing device,

providing a loader data file as an input to the downloading process, the loader data file including the at least one download parameter and the data to be downloaded,

providing an uploading process configured for uploading of data from a third data processing device to the first data processing device,

providing an uploading information file for the uploading of the data from the third data processing device, the uploading information file containing at least one upload parameter for indicating a source portion in the third data processing device containing the data from the third data processing device to be uploaded, and

providing the uploading information file as an input to the uploading process; and

wherein

the uploading process is configured to form at least one other loader data file as a result of the uploading process, and

the other loader data file is configured to be used as an input to the downloading process for downloading of data from the first data processing device.

6. The data processing device of claim 5, wherein the second device is a control device of an elevator system.

7. The data processing device of claim 5, wherein the second device comprises a control unit of the people conveyor system controlling at least one associated drive or door component of the system.

8. The people conveyor system of claim 5, wherein the people conveyor system is an elevator system.

9. A method in a people conveyor system for performing a data transfer between a first data processing device and a second data processing device, the second data processing device being a control device of the people conveyor system controlling at least part of a function of the people conveyor system, the method comprising the steps of:

providing a downloading process configured for downloading of data from the first data processing device to the second data processing device via a connection between the first data processing device and the second data processing device;

providing at least one download parameter for the downloading of the data, the at least one download parameter containing information for indicating a downloading destination on the second data processing device;

providing a loader data file as an input to the downloading process, the loader data file including the at least one download parameter and the data to be downloaded;

providing an uploading process configured for uploading of data from a third data processing device to the first data processing device;

providing an uploading information file for the uploading of the data from the third data processing device, the uploading information file containing at least one upload parameter for indicating a source portion in the third data processing device containing the data from the third data processing device to be uploaded; and

providing the uploading information file as an input to the uploading process; and

wherein

the uploading process is configured to form at least one other loader data file as a result of the uploading process, and

the other loader data file is configured to be used as an input to the downloading process for downloading of data from the first data processing device.

10. The method according to claim 9, wherein

the at least one download parameter includes address information for indicating a memory portion on the second data processing device in which the data to be downloaded is to be stored.

11. The method according to claim 9, wherein

the at least one download parameter includes information which allows for checking whether the data to be downloaded is correct.
