Migrating service groups


Migrating service groups
Prev	About administering service groups	Next

VCS provides live migration capabilities for service groups that have resources to monitor virtual machines. The process of migrating a service group involves concurrently moving the service group from the source system to the target system with minimum downtime.

To migrate a service group from one system to another

Type the following command:
```
# hagrp -migrate service_group -to system
```
A service group can be migrated only if it is fully online. The -migrate option is supported only for failover service groups and for resource types that have the SupportedOperations attribute set to migrate.

See Resource type attributes.

The service group must meet the following requirements regarding configuration:

A single mandatory resource that can be migrated, having the SupportedOperations attribute set to migrate and the Operations attribute set to OnOff
Other optional resources with Operations attribute set to None or OnOnly

The -migrate option is supported for the following configurations:

Stand alone service groups
Service groups having one or both of the following configurations:
- Parallel child service groups with online local soft or online local firm dependencies
- Parallel or failover parent service group with online global soft or online remote soft dependencies
