Redis - integration with Shopware 6.7 questions

Shopware 6 (English) General Questions (EN)

I am testing the integration of Redis with Shopware 6.7 and have several questions.
I am using two Redis instances: one for ephemeral data (cache) and one for persistent data.
My settings for persistent data are stored in config/packages/shopware.yaml

My first question is about switching the number_range to Redis, which belongs to the persistent instance. According to the Shopware 6.7 documentation:

Migrating between storages

You can migrate the current state of the number ranges from your current storage to a new one by running the following CLI command:

bin/console number-range:migrate {fromStorage} {toStorage}

For example, if you want to migrate from the default SQL storage to the high-performing Redis storage, the command is:

bin/console number-range:migrate SQL Redis

However, when I try to perform this migration after switching to Redis, I get the following error:

php bin/console number-range:migrate SQl Redis

[WARNING] Migrating the number range increments during load may lead to duplicate numbers being generated.

Are you sure you want to continue? (yes/no) [yes]:

yes

In IncrementStorageRegistry.php line 35:

[Shopware\Core\System\NumberRange\Exception\IncrementStorageNotFoundException]
The number range increment storage „SQl“ is not available. Available storages are: „redis“.

This seems to contradict the documentation.

  1. How should this migration be done correctly? Is it necessary to perform this migration at all?
  2. During a full project backup, whether for migrating to a development environment or restoring data to the project, we back up the files and perform a MySQL dump.
    After integrating Redis, should we also back up the Redis database separately?
