Linux & MacOs

1. Stop MyDexChain Node Docker Container (For Data Consistency):

docker kill mydexchain

2. Copy /var/lib/docker/volumes/mydexchain to Backup Path:

rsync -avzhHP /var/lib/docker/volumes/mydexchain/ /backup_path/mydexchain/

3. Start MyDexChain Docker Container on the New Docker Host :

docker run -d --rm -p 2020:2020 -v mydexchain:/var/lib/postgresql/ --privileged --log-driver=none --name mydexchain mydexchain/mydexchain:latest

4. Follow the Blocks :

docker attach mydexchain

Windows

1. Stop MyDexChain Node Docker Container (For Data Consistency):
