If you want to migrate your old mailcow installation to a new server you can follow this:
|
||
|
|
|
||
|
|
**1\.**
|
||
|
|
Install [Docker](https://docs.docker.com/engine/installation/linux/) and [Docker Compose](https://docs.docker.com/compose/install/) on your new server.
|
||
|
|
|
||
|
|
Quick installation for most operation systems:
|
||
|
|
|
||
|
|
- Docker
|
||
|
|
```
|
||
|
|
curl -sSL https://get.docker.com/ | CHANNEL=stable sh
|
||
|
|
# After the installation process is finished, you may need to enable the service and make sure it is started (e.g. CentOS 7)
|
||
|
|
systemctl enable docker.service
|
||
|
|
```
|
||
|
|
|
||
|
|
- docker-compose
|
||
|
|
```
|
||
|
|
curl -L https://github.com/docker/compose/releases/download/$(curl -Ls https://www.servercow.de/docker-compose/latest.php)/docker-compose-$(uname -s)-$(uname -m) > /usr/local/bin/docker-compose
|
||
|
|
chmod +x /usr/local/bin/docker-compose
|
||
|
|
```
|
||
|
|
|
||
|
|
Please use the latest Docker engine available and do not use the engine that ships with your distros repository.
|
||
|
|
|
||
|
|
**2\.** Make sure that Docker is stopped:
|
||
|
|
```
|
||
|
|
systemctl status docker.service
|
||
|
|
```
|
||
|
|
|
||
|
|
**3\.** Run the following commands on the source machine (take care of adding the trailing slashes in the first path parameter as shown below!):
|
||
|
|
```
|
||
|
|
rsync -aHhP --numeric-ids --delete /opt/mailcow-dockerized/ root@some.other.machine.net:/opt/mailcow-dockerized
|
||
|
|
rsync -aHhP --numeric-ids --delete /var/lib/docker/volumes/ root@some.other.machine.net:/var/lib/docker/volumes
|
||
|
|
```
|
||
|
|
|
||
|
|
**4\.** Shut down Mailcow via `docker-compose down` and stop Docker on the source machine.
|
||
|
|
**5\.** Repeat step 3 with the same commands (this will be much quicker than the first time).
|
||
|
|
**6\.** Start docker on the target machine `systemctl start docker.service`.
|
||
|
|
**7\.** Go into the /opt/mailcow-dockerized directory and run `docker-compose pull`.
|
||
|
|
**8\.** Start the whole mailcow stack with `docker-compose up -d` and everything should be fine.
|
||
|
|
**9\.** Change your DNS settings.
