import backup

All backup parts are simply compressed directories and can be unpacked (or simply rsynced from another host). Only database dump need to be imported.

Rsync command:

rsync -r -a -v -e ssh root@REMOTE:/var/db/openproject/files/ /var/db/openproject/files

import mysql dump

apt-get install mysql-server

mysql

CREATE USER 'openproject'@'localhost' IDENTIFIED BY 'password';
CREATE DATABASE openproject CHARACTER SET utf8mb4;
GRANT ALL PRIVILEGES ON openproject.* TO 'openproject'@'localhost';
\q

Configure openproject for mysql:

store original postgresql somewhere:
```
openproject config:get DATABASE_URL
```

openproject config:set MYSQL_DATABASE_URL="mysql2://openproject:password@127.0.0.1:3306/openproject"

openproject config:set DATABASE_URL="mysql2://openproject:password@127.0.0.1:3306/openproject"

```
openproject run rake db:create:all
```

Restore backup dump:

zcat mysql-dump-20191211011301.sql.gz | mysql -u openproject -p openproject

Restart service:

systemctl restart openproject

Set database URL to previously created postgresql database:

openproject config:set DATABASE_URL=postgres://openproject:...@127.0.0.1:45432/openproject

Migrate database:

sudo openproject run ./docker/mysql-to-postgres/bin/migrate-mysql-to-postgres

Remove mysql:

apt-get remove mysql-server
openproject config:unset MYSQL_DATABASE_URL
