Runtime migration supports the migration of stand-alone environments and network deployment environments.
Stand-alone migration
- Side-by-side migration: where the source and target of the migration are on the same system
- Remote migration: where the source and target of the migration are on different systems
Operating system upgrade migration: where the
operating system on the source system is being upgraded during the
migration procedure to a new version that is supported by IBM® Business Process Manager V8.0.1.
- Stand-alone side-by-side migration
- The stand-alone side-by-side migration process is the simplest runtime migration scenario, where the target product is installed on the same system as the source product, and the runtime migration procedures and tools are used to migrate the stand-alone profile containing the configuration, applications and the product databases to the target environment.
- Stand-alone remote migration
- The stand-alone remote migration process enables IBM Business Process Manager V8.0.1 to be
installed on a different system from the source of the migration in
order to support migration of the configuration and applications from
one system to another. The stand-alone remote migration process can
be used to support a variety of scenarios including:
- Migrating to a remote system that has the same type of hardware, operating system, and operating system version as the source of the migration
- Migrating to a remote system that has a different type of hardware (for example, 64-bit), a different operating system, or a different operating system version
The process requires the migration commands on the target system to be copied to the source system, where they are used to copy the source profiles. The snapshot directory is copied to the target system and used as the source for the profile migration.
- Stand-alone operating system upgrade migration
- The stand-alone operating system upgrade migration process enables
the operating system on the system that contains the source of the
migration to be upgraded during the migration process. This is typically
necessary if the operating system version containing the source product
version is no longer supported by IBM Business Process Manager V8.0.1.
This process requires that you copy each of the source profiles on the prior version of the operating system, back up the copied source profiles to a remote location, reinstall the operating system to the new version, install the target product, restore the copied source profiles back to the migration system with the updated operating system, and then use the snapshot directory as the source for the profile migration.
Network deployment migration
Network deployment environment migrations are more involved than stand-alone environment migrations because of the need to migrate the deployment manager, clusters, nodes, and differently scoped product databases, in the appropriate order. The side-by-side migration, remote migration, and operating system upgrade migration also are supported for network deployment environments. All network deployment migrations require IBM Business Process Manager V8.0.1 to be installed side-by-side with the source product of the migration or a different system. If the source of the migration is augmented by additional BPM products, they should be installed in the same installation directory as IBM Business Process Manager V8.0.1.
Two different types of nodes are referred to in the network deployment migration procedures, clustered nodes and non-clustered managed nodes. Clustered nodes contain at least one server that is a member of a cluster. Non-clustered managed nodes do not contain any servers that are cluster members.
