To prepare for migration, work with your

NSX

administrator. Each migration plan requires input to and output from the

NSX Data Center Migration Coordinator (was NSX-T Data Center Migration Coordinator)

utility in

NSX

. During migration, the migration plan on-screen help informs you when to share data files with the

NSX

administrator.

Coordination between you, as the

VMware Aria Automation

administrator, and the

NSX

administrator is helpful for successful migration. Inform them of your plans so that they can make time in their schedule to help you by importing and exporting files in the

NSX Data Center Migration Coordinator (was NSX-T Data Center Migration Coordinator)

utility, which is the utility that performs the underlying

NSX

migration. During step 4 in the migration plan, you and the

NSX

administrator must share

NSX Data Center Migration Coordinator (was NSX-T Data Center Migration Coordinator)

files with one another, as described in Creating and running the VMware Aria AutomationNSX-V to NSX-T migration plan. For more information about the

NSX Data Center Migration Coordinator (was NSX-T Data Center Migration Coordinator)

, see Migrating NSX Data Center for vSphere (NSX-V) with vRealize Automation in the VMware NSX product documentation.

Before you can migrate your

NSX-V

cloud accounts to

NSX-T

using the

VMware Aria Automation

NSX-V

to

NSX-T

migration assistant, you must create a new and unassociated

NSX-T

target cloud account in

VMware Aria Automation

for each source

NSX-V

cloud account.

Add a new target

NSX-T

cloud account to

VMware Aria Automation

for each source

NSX-V

cloud account in your

VMware Aria Automation

projects.

You must create one target

NSX-T

cloud account for each source

NSX-V

cloud account to be migrated. You specify the 1:1 mapping from a source

NSX-V

cloud account to a target

NSX-T

cloud account when you create the migration plan. Each 1:1 cloud account mapping requires its own separate migration plan. The plan step is described in Creating and running the VMware Aria AutomationNSX-V to NSX-T migration plan.

The target
NSX-T
cloud account must be at
NSX Data Center
version 3.1.1 or higher.
You must specify the
Policy API method
option when you create the target
NSX-T
cloud account. The
Manager API method
is not supported by the migration utility for a target
NSX-T
cloud account.
The target
NSX-T
cloud account
must not
be associated to a
vCenter
cloud account. You create that association later in the process.
The
NSX-T
cloud account specified must not be in use by a
VMware Aria Automation
deployment.

For information about how to create an

NSX-T

cloud account, see

Using Automation Assembler

.

By starting the

VMware Aria Automation

NSX-V

to

NSX-T

migration utility, you begin to populate the

NSX

migration plan by following the perspective on-screen instructions and prompts.

The

NSX

migration plan guides you through the following required steps:

Configure source and target cloud accounts.
Run an assessment to determine readiness for migration.
Enter maintenance mode for the cloud accounts.
Transfer configuration and mapping files to and from your
NSX
administrator.
Run migration to map source
NSX-V
objects to new target
NSX-T
objects.
Test your system.
Exit maintenance mode for the cloud accounts.
