Convert automatically all GRASS 6 vector maps to GRASS 7 (including attribute transfer from DBF to SQLite)
To become usable in GRASS 7, all vector maps in a mapset need to be updated to the improved vector file format (i.e., rebuild the topology with v.build.all along with the change to the SQLite database backend (new default in GRASS 7 instead of DBF in GRASS 6, using db.connect and v.db.reconnect.all).
Run this in GRASS 7:
# first rebuild topology for all vector maps
v.build.all
# set new default db connection (from DBF to new SQLite default)
db.connect -d
# copy attribute tables from old DB to new SQLite DB, delete old tables in DBF format
v.db.reconnect.all -cd
