Restoring a cluster from a backup archive

If you backed up the primary server before you migrated or reverted the cluster, you can restore the primary server from the backup archive if migration or reversion fails. After you restore the primary server, you must recreate the other servers in the high-availability cluster.

To restore a cluster from a level-0 backup archive:

1. Point your INFORMIXDIR, PATH, and any other relevant environment variables to the directory in which the original version of Informix® was installed before you migrated or reverted.
2. Using the level-0 backup archive, perform a full restore of your primary server.
3. Recreate the rest of your high-availability cluster.
