Migrate from In-Memory DB v1 to v2

Important:

• In-Memory DB v2, powered by Valkey, is now available, bringing Valkey (Redis®-compatible) engines in versions 8, 8.1, and 9. It also adds extended snapshot retention and native IONOS CLOUD Observability integration.
• Use In-Memory DB v2 to create clusters using either the DCD or the API.
• Creation of clusters using In-Memory DB v1 is deprecated through the DCD and only limited operations are supported on legacy clusters.
• Creation of v1 clusters through the API will be deprecated as of July 31, 2026.
• An automatic migration from v1 to v2 is impossible. You must manually migrate existing v1 clusters to the new v2 infrastructure through the v2 API. For step-by-step instructions, see Manual migration.

Manual migration

You must perform the migration through the In-Memory DB v2 API.

Important: Creation of v1 clusters through the API will be deprecated as of July 31, 2026. Migrate existing clusters to v2 before this date.

Prerequisites:

• You must have the contract administrator or owner role, or the Access and manage DBaaS privilege, to manage clusters.
• The v2 API requires API token authentication (tokenAuth). Include a valid token in the Authorization header of every request. For information on generating tokens, see the Authentication API.

1. Create a new In-Memory DB v2 instance using the v2 API. For the API documentation, see In-Memory DB v2 Cloud API.

2. If you want to move data from your v1 instance, migrate it to the new In-Memory DB v2 instance.

3. Update your applications to connect to the new In-Memory DB v2 Endpoints.

Note: Updating your applications to the new endpoint may briefly interrupt connections. Plan for a short cutover window while traffic switches from v1 to v2.
