I want to know if I upgrade xibo with docker to a new version in the following way
Stop the running container
cd /opt/xibo
docker-compose stop
Backup the existing container data
cd /opt
cp -rp xibo xibo-1.8.0-backup
Download the new docker-compose files
cd /opt/xibo
wget https://github.com/xibosignage/xibo-cms/releases/download/1.8.1/xibo-docker.tar.gz
tar --strip 1 -zxvf xibo-docker.tar.gz
docker-compose up -d
Is my media files still exist??
