Please be adviced that this guide is a first draft. Mailcow: dockerized changed quite a lot on its DB configuration. It now uses the InnoDB file format `Barracuda` and the `utf8mb4` character set. There is also some change to the DB / TABLE structure.
|
|
|
|
!!! info
|
|
Also note that this guide doesn't touch on the users settings like *Spamlevels*, *TLS Settings*, etc. nor the export / import of your roundcube or SOGo settings.
|
|
|
|
Lastly please check the section on how to [import / restore](backup_maildir/#restore) your maildir backup to get an idea how to migrate your mails.
|
|
|
|
## Create mailcow db backups
|
|
|
|
First you need to modify the table `mailcow`. Mailcow-dockerized adds three and moves two existing columns in the table `mailbox`. The columns `tls_enforce_in` and `tls_enforce_out` get moved two rows up (behind `domain`). The columns `key`, `multiple_bookings` and `wants_tagged_subject` need to be added after `tls_enforce_out`.
|
|
|
|
It should look like this:
|
|
|
|
```
|
|
MariaDB [mailcow]> desc mailbox;
|
|
+----------------------+--------------+------+-----+-------------------+-----------------------------+
|
|
| Field | Type | Null | Key | Default | Extra |
|
|
+----------------------+--------------+------+-----+-------------------+-----------------------------+
|
|
| username | varchar(255) | NO | PRI | NULL | |
|
|
| password | varchar(255) | NO | | NULL | |
|
|
| name | varchar(255) | YES | | NULL | |
|
|
| maildir | varchar(255) | NO | | NULL | |
|
|
| quota | bigint(20) | NO | | 0 | |
|
|
| local_part | varchar(255) | NO | | NULL | |
|
|
| domain | varchar(255) | NO | MUL | NULL | |
|
|
| tls_enforce_in | tinyint(1) | NO | | 0 | |
|
|
| tls_enforce_out | tinyint(1) | NO | | 0 | |
|
|
| kind | varchar(100) | NO | | | |
|
|
| multiple_bookings | tinyint(1) | NO | | 0 | |
|
|
| wants_tagged_subject | tinyint(1) | NO | | 0 | |
|
|
| created | datetime | NO | | CURRENT_TIMESTAMP | |
|
|
| modified | datetime | YES | | NULL | on update CURRENT_TIMESTAMP |
|
|
| active | tinyint(1) | NO | | 1 | |
|
|
+----------------------+--------------+------+-----+-------------------+-----------------------------+
|
|
```
|
|
|
|
You can do this with a UI like [Adminer](https://www.adminer.org/#download) or use the MySQL CLI like :
|
|
|
|
```
|
|
MariaDB [mailcow]> ALTER TABLE mailbox MODIFY COLUMN tls_enforce_in TINYINT(1) NOT NULL DEFAULT '0' AFTER domain,
|
|
MODIFY COLUMN tls_enforce_out TINYINT(1) NOT NULL DEFAULT '0' AFTER tls_enforce_in;
|
|
MariaDB [mailcow]> ALTER TABLE mailbox ADD COLUMN `kind` VARCHAR(255) NOT NULL AFTER `tls_enforce_out`,
|
|
ADD COLUMN `multiple_bookings` TINYINT(1) NOT NULL DEFAULT '0' AFTER `kind`,
|
|
ADD COLUMN `wants_tagged_subject` TINYINT(1) NOT NULL DEFAULT '0' AFTER `multiple_bookings`;
|
|
MariaDB [mailcow]> DESC mailbox;
|
|
```
|
|
|
|
When this is done we can backup the tables:
|
|
|
|
```bash
|
|
# Load your mysql variables into environment
|
|
DBHOST=$(grep database_host /var/www/mail/inc/vars.inc.php | cut -d'"' -f2)
|
|
DBNAME=$(grep database_name /var/www/mail/inc/vars.inc.php | cut -d'"' -f2)
|
|
DBUSER=$(grep database_user /var/www/mail/inc/vars.inc.php | cut -d'"' -f2)
|
|
DBPASS=$(grep database_pass /var/www/mail/inc/vars.inc.php | cut -d'"' -f2)
|
|
|
|
# Backup your tables
|
|
mysqldump --replace --no-create-info --default-character-set=utf8mb4 \
|
|
--host &{DBHOST}-u${DBUSER} -p${DBPASS} ${DBNAME} \
|
|
alias alias_domain domain domain_admins mailbox quota2 sender_acl > backup_mailcow.sql
|
|
```
|
|
|
|
- **--replace**: Write `REPLACE` statements rather than `INSERT` statements
|
|
- **--no-create-info**: Don't write `CREATE TABLE` statements.
|
|
- **--default-character-set** make sure our exported default charset is *utf8mb4*.
|
|
|
|
|
|
## Prepare mailcow: dockerized
|
|
|
|
To initiate your fresh installed database, visit **https://${MAILCOW_HOSTNAME}** with a browser of your choice. Check if the DB is initiated correctly afterwards:
|
|
|
|
```
|
|
# source mailcow.conf
|
|
# docker-compose exec mysql-mailcow mysql -u${DBUSER} -p${DBPASS} ${DBNAME}
|
|
MariaDB [mailcow]> show tables;
|
|
+-------------------------------+
|
|
| Tables_in_mailcow |
|
|
+-------------------------------+
|
|
| admin |
|
|
| alias |
|
|
[...]
|
|
```
|
|
|
|
## Import your backups:
|
|
|
|
```
|
|
# source mailcow.conf
|
|
# docker exec -i $(docker-compose ps -q mysql-mailcow) mysql -u${DBUSER} -p${DBPASS} ${DBNAME} < backup_mailcow.sql
|
|
```
|
|
|
|
Recalculate used quota with `doveadm`:
|
|
|
|
```
|
|
# docker-compose exec dovecot-mailcow doveadm quota recalc -A
|
|
```
|
|
|
|
Restart services:
|
|
|
|
```
|
|
# docker-compose restart
|
|
```
|
