Comment 5 for bug 2011824

we changed the default value in tempestconf because we assumed that the migration works everywhere (that it works on more deployments than the number of deployments where it doesn't work).

If it doesn’t work in your case, and we are sure that it’s not supposed to, just set the opt explicitely to false (as it was previously done by tempestconf by default)
