As a precaution, you should always back up the PostgreSQL database that you use with Cloud Manager before you upgrade to a newer version of Cloud Manager.
For more information about backing up a PostgreSQL database, see the PostgreSQL documentation. The following specific instructions are helpful in this process:
If you chose to automatically configure the PostgreSQL database during the initial Cloud Manager installation, the PostgreSQL password is located in the /etc/opt/netiq/cloudmanager/etc/pgusr.in file.
If the PostgreSQL DBMS you are using has several databases, you can list the database names using the following command:
sudo -u postgres psql -l
The Cloud Manager database name should contain the phrase cloudmanager. This is the database you want to back up.
When you identify the Cloud Manager database you want to back up, use a command similar to the following to back it up:
sudo -u postgres pg_dump -s cloudmanager > /var/opt/netiq/cloudmanager/cm_database_backup.dump.out
