You need to create migration volume so that the tool can store backups and meta data. If the container is deleted, the data still persists because it is stored outside the container.
Create a folder named migrationVolume
in the Host machine.
If you are using Linux based Host, run the following commands. For other OS such as Windows, use OS specific commands.
mkdir migrationVolume
Provide permissions for migrationVolume
so that the container can write into this volume.
chmod o+rwx migrationVolume
If you are staging 3.1 OVA locally on file system, ensure that the OVA is copied to this folder
migrationVolume
so that migration container can access.
