The PostgreSQL database is upgraded to 9.4 on the OES 11 SP3 server. The Archive and Version Services on an OES 2 and earlier OES 11 server uses the earlier versions of PostgreSQL and requires scripts to back up and restore the database on the OES 11 SP3 server. To avoid data loss, ensure that you back up the database before upgrading.
For more information, see Upgrade
in the OES 11 SP3: Novell Archive and Version Services Administration Guide.
