## ACME V2 migration
During migration from ACME V1 to ACME V2 with a storage file, a backup is created with the content of the ACME V1 file.
To obtain the name of the backup file, Træfik concatenates the option `acme.storage` and the suffix `.bak`.
For example : if `acme.storage` value is `/etc/traefik/acme/acme.json`, the backup file will be named `/etc/traefik/acme/acme.json.bak`.
!!! note
When Træfik is launched in a container, do not forget to create a volume of the parent folder to get the backup file on the host.
Otherwise, the backup file will be deleted when the container will be stopped and Træfik will not generate it again.
