Best Practices Guide › DMM Best Practices › Planning the Migration Method

Planning the Migration Method

CA DMM supports two types of migrations. With either of these migration methods, CA DMM can be installed on the computer hard drive or it can be accessed from a central network location.

Deferred Migrations

Performing a deferred migration is considered best practice where one or more of the following situations exist:

• The source computer and the destination computer have the same hardware. The source computer is going to be ‘wiped and reloaded’ with a new operating system or applications.
• The DNA file can be created and saved to a storage device such as another computer, a server location (such as a file server, network appliance, or an Apache Web server), removable media for later retrieval.

Real-Time Migrations

Performing a real-time migration is considered best practice where one or more of the following situations exist:

• Two separate computers are involved and both exist on a common network.
• Two computers are involved and they can be connected directly to each other with a crossover cable.
• Two computers can have different hardware and operating systems.

  This method is the best solution when you are refreshing hardware and/or moving to a new operating system and/or applications.
