List of Content Delivery relational databases to upgrade and Content Delivery indexes to migrate

A list of relational databases and indexes required by various Content Delivery microservices.

Content Delivery requires the following relational databases and indexes:
NameDescription
Discovery databaseThis database contains information about the various Content Delivery Capabilities and where to find them.
Content Data StoreThis database contains published content.
State Store databaseThis database is used by Content Deployer, and, by default, shares a database with the Content Data Store.

But in some cases, you may want to have a State Store database that is separate from the Content Data Store, and use it instead of the one that was installed along with the Content Data Store. In a test environment, you may want to have separate databases in order to more easily isolate the source of a database problem when debugging. In a production environment, you may want to have separate databases in order to improve performance.

Elasticsearch (now OpenSearch) search indexesThese indexes are used by the Content Delivery search feature.
