Migration considerations

There are a number of ways in which you can migrate HCL to a newer version. Some migration scenarios might offer a higher availability percentage over another. There are some scenarios where the migration can be done in parallel while your source environment remains in production. Other scenarios might require the production system to be disconnected just before you go live with the newly migrated system. Depending on your needs on high availability systems, you might choose one approach or another.

Refer to the Server topologies section of this documentation for details on high availability installations.
