THe synopsis reads:

ogr2ogr [--help-general] [-skipfailures] [-append] [-update]
         [-select field_list] [-where restricted_where|\@filename]
         [-progress] [-sql <sql statement>|\@filename] [-dialect dialect]
         [-preserve_fid] [-fid FID] [-limit nb_features]
         [-spat xmin ymin xmax ymax] [-spat_srs srs_def] [-geomfield field]
         [-a_srs srs_def] [-t_srs srs_def] [-s_srs srs_def] [-ct string]
         [-f format_name] [-overwrite] [[-dsco NAME=VALUE] ...]
         dst_datasource_name src_datasource_name
         [-lco NAME=VALUE] [-nln name]
         [-nlt type|PROMOTE_TO_MULTI|CONVERT_TO_LINEAR|CONVERT_TO_CURVE]
         [-dim XY|XYZ|XYM|XYZM|2|3|layer_dim] [layer [layer ...]]

the line "dst_datasource_name src_datasource_name" indicates that you
specify the destination filename and then the source filename
(note the order).
