The NSX Intelligence traffic flow data migration did not complete successfully.

Problem

The system encountered an error while attempting to migrate the traffic flow data from the previous NSX Intelligence 1.2.x installation. The Migration Failed error message, along with a reason for the failure, appears on the NSX Intelligence feature card.

Cause

There can be any one of the following reasons why the migration failed.
  1. The NSX Intelligence 1.2.x appliance is down during the time the migration was attempted.
  2. The appropriate ports are not open on the NSX Intelligence 1.2.x appliance.
  3. Network latency might have caused the migration to time out.

Solution

Fix the issue displayed with the Migration Failed error message and retry the traffic flow data migration again.
