# Replacing Maps

During the network design process, it's common for newer or better floorplans to become available. While Hamina Network Planner doesn't yet offer a map replacement or "swap map" feature, it is still possible to replace maps in a project under certain conditions.

## Map Replacement Feasibility

Whether the map can be replaced depends on the type and contents of the project, due to certain limitations in Hamina Network Planner, or external factors such as network infrastructure API support.

## Map Replacement&#x20;

1. Upload the new map to the project. The project will now contain the old map, and the new map.

2. Use the **Scale** tool to measure a reference point on the old map that exists on the new map, such as the length or width of the building, or of a long hallway. The longer, the better. *<mark style="background-color:$warning;">Note: Getting an exact measurement is critical.</mark>*

3. Switch to the new map, and use the scale on the same reference points. *<mark style="background-color:$warning;">Note: Selecting the exact same reference points, and setting the scale with precision is critical</mark>*<mark style="background-color:$warning;">.</mark>

4. Switch back to the old map, and make sure that all map layers are visible.

5. Press <kbd>Command + A</kbd> or <kbd>Ctrl + A</kbd> to select all.

6. Press <kbd>Command + C</kbd> or <kbd>Ctrl + C</kbd> to copy everything to the clipboard.

7. Switch to the new map.

8. Press <kbd>Command + V</kbd> or <kbd>Ctrl + V</kbd> to paste everything on the map.

9. The contents of the clipboard will be placed on the map and selected, but will need to be moved to the correct position. Find a non-point to click and drag, moving the entire selection into place on the new map.<br>

10. Once you satisfied with the changes, you can delete the old map and repeat the process for any other maps or floors in the project.
