After you have imported the configuration from your NSX-Venvironment, you must review and resolve the reported configuration issues before you can continue with the migration.

On the Resolve Configuration page, two types of configuration issues are reported.
Blocking Issues
As the name suggests, these issues block the migration, and they must be fixed for the migration to proceed. You might have to change the configurations in your NSX-V environment before you can migrate to NSX-T.
Warnings
These configuration issues are organized into several categories, and each category can have one or more configuration items. You should provide inputs to fix the warning messages that are displayed for the configuration items, or choose to skip the warnings, if needed. The input you provide determines how the NSX-T environment is configured.
