Cheers

There are several methods to do this.
You could extract the x/y values (for points this is easy) in the
field calculator and change the coordinates with the new vectors and
then write that back into the geometry itself. Then create a WKT
geometry string (something like "POINT(coordx coordy)") and use
geom_from_wkt in the field calculator to write this back into the
geometry.
Or alternatively export the thing in a CSV, do the calculation in the
spreadsheet and load the layer back.
Whatever you do: have a look at the field calculator - it is very
powerful!
Hope this helps,
Andreas

Hi Natalia,
try the Plugin "Vector Bender".
It does to vectors what georefencers does to raster.
Good luck!
