Thank you very much!

> Dear Veronica,

> mv /home/veroandreo/grassdata//ll_wgs84/PERMANENT/tgis/sqlite.db \
>      /home/veroandreo/grassdata//ll_wgs84/PERMANENT/tgis/sqlite.db.backup

> A new temporal database with the same name will be created, when you
> invoke any temporal command. You can access any data in the old
> database using a sqlite client application, or open office. You will
> need to install the grass7 svn version from August 2013, to use the
> old temporal database within grass7.
