Migrating Redis databases to cloud databases

You can migrate Redis databases to Selectel cloud databases.

Connect to Redis. If you use a password, specify it in an environment variable:
```
export REDISDUMPGO_AUTH=<password>
```
Specify < password > is the password of the source cluster user.
Create a dump of the source cluster using the redis_dump_go utility:
```
redis-dump-go \
      -host <host> \
      -port <port> \
      > redis_backup.txt
```
Specify:
- <host> - The IP address or DNS name of the source cluster master host;
- <port> - port.

Restore the dump to the receiving cluster:

redis-cli \
        -a <password> \
        -h <host> \
        -p <port> \
        --tls \
        --cacert <cacert> \
        --pipe \
        < redis_backup.txt

Specify:

<password> - password of the user of the receiving cluster;
<host> - The IP address or DNS name of the master host of the host cluster;
<port> - port;
<cacert> - root certificate.
