How to georeference a vector layer using QGIS?
To georeference a vector layer, try the qgsAffine plugin. There is more info at Where to find qgsaffine in the menu? I recommend the Vector Bender plugin for QGIS. I tried it and it works fine and is user friendly. Depending on amount of pair of points that you define, you can either do:
How to georeference a map using a raster file?
To georeference the map: Open the georeference tool, Raster ‣ Georeferencer ‣ Georeferencer. Add the map image file, rautjarvi_map.tif, as the image to georeferenciate, File ‣ Open raster. When prompted find and select the KKJ / Finland zone 2 CRS, it is the CRS that was used in Finland back in 1994 when this map was created.
How to convert a vector file to an ESRI shapefile?
Georeferencing the vector file To work with the vector file we need to convert it to an ESRI Shapefile with QGIS. Open QGIS and add the dxf file as a raster layer, select DHDN / Gauss-Kruger zone 3 (EPSG:31467) as the coordinate system. Right click the layer, save as ESRI Shapefile.
How to add a DXF file as a raster layer?

How to generate Georeferencer GDAL plugin in QGIS?
Generate a set of GCP pairs, with one point being the original location in the ungeoreferenced vector file, and the other point being the desired location in your georeferenced workspace. There are a variety of ways to generate GCPs. I used the Georeferencer GDAL plugin in QGIS.
