The answer to this depends on the architecture of the environment. Environments designed with fully redundant components and services can be migrated in a phased approach with minimal or no downtime.

For environments without full redundancy, SilverBack Migration Solutions, Inc works with our customers to develop the most effective plan based on customer environment architecture.

Examples include:

• A phased migration solution to compartmentalize services and minimize downtime in planned maintenance windows.
• Use of virtualization to logically shift critical services within the environment in order to free a portion of the hardware to be moved in a phased approach. Once the free hardware is up and running in the new environment, virtualized services are logically moved again to free the remaining hardware in the old location which is then physically migrated. This process can be repeated multiple times as needed.
• SilverBack Migration Solutions, Inc specializes in rapid "forklift" moves of entire environments in cases where a maintenance window can be arranged. Even large environments can be fully migrated depending on transport distances in 24-72 hours.
