# v.convert(1grass)

Imports older versions of GRASS vector maps.

## NAME

**v.convert**  - Imports older versions of GRASS vector maps.

## KEYWORDS

**v.convert**\
 **v.convert help**\

- **--verbose**

  Verbose module output

- **--quiet**

  Quiet module output

### Parameters:

- **input**=*name*

  Name of input vector map

- **output**=*name*

  Name for output vector map

- **endian**=*string*

  Endian of input vector map\
   Options: *big,little*\
   Default: *big*

## DESCRIPTION

*v.convert* converts GRASS 5.0/5.3/5.4 vectors into 5.7/6.x vectors.

## NOTES

Vector maps from 5.0/5.3/5.4 and 5.7/6.x do not interfere. They are stored in different  directories, so you can use the same names. Old vector maps can be listed with *g.list oldvect*.

If you need to convert back from 5.7/6.x into the 5.0/5.3/5.4 vector format, use *v.out.ogr* (to SHAPE format) and then *v.in.shape* in the old GRASS program. Alternatively use "*v.out.ascii -o*" and *v.in.ascii*.

As this GRASS version uses SQL for attribute management, there are some SQL restrictings concerning the file names.

Missing centroids can be added with *v.category*.

## EXAMPLE

`v.convert in=vectormap_from_50 out=vectormap_60`\

## SEE ALSO

g.list, v.category, v.convert.all, v.out.ascii, v.in.ascii, v.out.ogr
