Hi,

Check out the documentation for "Copying Data" and see if it helps It explains how to copy tables that have identity columns.

Thanks Jim,
I don't have connectivity set up between servers

dbadmin=> CONNECT TO VERTICA <> USER dbadmin PASSWORD '<>' ON 'ip_address',5433;
CONNECT
dbadmin=> COPY test_1 FROM VERTICA test_1 DIRECT;

dbadmin=> COPY test_1 FROM VERTICA test_1 DIRECT;
ROLLBACK 4236: One or more nodes did not open a data connection to this node. This may indicate a network configuration problem. Check that the private interfaces used for communication among the cluster hosts reside in the same subnet and are returned first by host address lookup
ERROR 4789: [dbname] Statement is canceled

To avoid this issue i plan to manually create dump in csv file and import the data from csv in another server.
