About merging hosts
Merging hosts improves agentless ability to associate host names with automatically created host
groups.
WWN names that are registered to multiple hosts can be merged into one destination host. The source
host will be deleted upon completion of the merge.
Information about WWN names are also merged. If the host that is monitored by the Host Data
Collector or Device Manager agent is merged as a source host, the source IP address will not be
migrated.
Prerequisites for merging hosts
