**While not recommended**, if you wish to manually migrate your xCAT database, see the following documentation:
`Manually set up PostgreSQL <https://sourceforge.net/p/xcat/wiki/Setting_Up_PostgreSQL_as_the_xCAT_DB/#manually-setup-postgresql>`_
Setting up the Service Nodes
----------------------------
For service nodes, add the IP address of each service nodes to the postgres configuration file: ``/var/lib/pgsql/data/pg_hba.conf``
If you had the following two service nodes: ::
sn10 192.168.1.10
sn11 192.168.1.11
You would add the following to ``/var/lib/pgsql/data/pg_hba.conf`` ::
host all all 11.16.1.230/32 md5
host all all 11.16.2.230/32 md5
Restart PostgreSQL after editing the file: ::
service postgresql restart
For more information about changing the ``pg_hab.conf`` file and ``postgresql.conf`` files, see the following documentation:
`Setup the PostgreSQL Configuraion Files <https://sourceforge.net/p/xcat/wiki/Setting_Up_PostgreSQL_as_the_xCAT_DB/#setup-the-postgresql-configuration-files>`_
