Upgrading the GRASS database from older to recent GRASS versions

Migrating from GRASS 4 to GRASS 5

Raster: The LZW compression has been removed which requires a format conversion: see announcement from Jan. 2001.

Raster3D: No changes.

Sites: No changes.

Vector: You need to rebuild the topology with v.support.

Migrating from GRASS 4 to GRASS 6

Raster: The LZW compression has been removed which requires a format conversion: see announcement from Jan. 2001.

Raster3D: No changes.

Sites: Sites have been deprecated and are handled as vector points. Convert sites maps to vector maps with v.in.sites (for all maps, use v.in.sites.all).

Vector: You need to convert the format with v.convert (for all maps, use v.convert.all).

Migrating from GRASS 5 to GRASS 6

Raster: No relevant changes.

Raster3D: No changes.

Sites: Sites have been deprecated and are handled as vector points. Convert sites maps to vector maps with v.in.sites (for all maps, use v.in.sites.all).

Vector: You need to convert the format with v.convert (for all maps, use v.convert.all).

Migrating from GRASS 6 to GRASS 7

Raster: No changes.

Raster3D: No changes.

Vector: You need to rebuild the topology with v.build (for all maps automatically: v.build.all).

Migrating from GRASS 7 to GRASS 8

So far GRASS GIS 8 is not yet under development.

See GRASS 8 planning: ideas

Troubleshooting

  • "XXX is not a valid mapset" error:
This normally indicates that the directory lacks a WIND file. Copying the DEFAULT_WIND file (if it exists) to WIND should suffice.
