Migrating Redis databases to Managed Databases for Redis

You can migrate Redis databases to Selectel Managed Databases.

Connect to Redis. If you use a password, specify it in the environment variable:
```
export REDISDUMPGO_AUTH=<password>
```
Specify <password> — the source cluster user password.
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 target cluster:

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

Specify:

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