Bloomreach12 Elasticsearch minimum requirements

Hi there!

My client is running Bloomreach Experience Enterprise version 12 (12.6.9) and we make use of Relevance and integrated Elasticsearch in our search functionality.

We would like to upgrade our Elasticsearch database from 5.2.2 to 6.x
I read on https://documentation.bloomreach.com/12/library/enterprise/enterprise-features/targeting/data-stores/sql-data-store.html that relevance requires MySQL 5.6
But on https://documentation.bloomreach.com/12/library/about/system-requirements.html it states that Relevance requires MySQL 5.7 or 8

Could you please confirm if version MySQL 5.7 or 8 is minimally required in our case?

Thanks in advance.

Greetings,
Eric
