ovdb_upgrade - Perform any needed upgrades on the ovdb database
The ovdb_upgrade command is be used to upgrade the ovdb database when
migrating to a newer version of the BerkeleyDB library (in which there is
a change in BerkeleyDB's internal db format).
The upgrade is done in-place, and is not reversable.
Here is an example procedure to upgrade a database created with BerkeleyDB
2.x to use BerkeleyDB 3.x:
Install BerkeleyDB 3.x
Do a `make clean' in the INN source tree
If BerkeleyDB 3.x is installed into a different path than the 2.x version,
run configure again, specifying the new path. For example:
`./configure --with-berkeleydb=/usr/local/BerkeleyDB.3.x [... other options]'
Shut down INN (e.g., with `rc.news stop'). Be sure to kill all nnrpds as
Do a `make update' to build INN with the new BerkeleyDB version and install
the new binaries.
