【Heroku】redisのアップグレード対応

ある日メールが来た

Hello 👋
We are reaching out again regarding your Redis database redis-angular-30647 on 〇〇 that requires a version upgrade.
Your Redis database redis-angular-30647 on 〇〇 is running a deprecated version (6.0.19) and will not be supported after 30 Jun, 2023.
Redis (6.0.19) will not be supported in less than a month.
We recommend upgrading your Redis database to the latest version supported by Heroku, which is currently 7.0.11. We perform heavy testing and validation work on all new Redis releases, including testing the upgrade procedure, and are careful to only recommend versions that we trust.
You can upgrade your Redis database to the latest default version by using heroku redis:upgrade command. You can read more about this procedure in our Dev Center article.
If you do not take action, we will schedule an upgrade to your Redis database on 30 May, 2023.
The upgrade will create a maintenance that will run during your next maintenance window. You can trigger it yourself beforehand by using the maintenance cli.
Please open a ticket if you have any questions about this process.
Thank you for choosing Heroku.
The Heroku Team
