How to Resize Vultr Managed Databases for MySQL

Updated on 27 August, 2025

Resizing Vultr Managed Databases for MySQL allows you to scale your database resources as your data grows. Scaling up is useful if your current database plan can't handle your workload. Upsizing your managed database cluster adds more CPUs, RAM, storage, and replica nodes to provide a better experience to your end-users.

Follow this guide to resize Vultr Managed Databases for MySQL using Vultr Customer Portal, API, CLI, or Terraform.

  • Vultr Customer Portal
  • Vultr API
  • Vultr CLI
  • Terraform
  1. Navigate to Products and select Databases.
  2. Click the target database instance.
  3. Navigate to Settings and click Change Plan.
  4. Review the active plan, select a new plan, set replica nodes, and click Save.

  1. List all the database instances by sending a GET request to the List Managed Databases endpoint and note the database ID. For example, 43b4c774-5dff-4ac0-a01f-78a23c2205b5.

    console 
    $ curl "https://api.vultr.com/v2/databases" \
    -X GET \
    -H "Authorization: Bearer ${VULTR_API_KEY}"

  2. Send a PUT request to the Update Managed Database endpoint to change the database plan and specify the database ID and the new plan (For instance, vultr-dbaas-business-cc-1-55-2).

    console 
    $ curl "https://api.vultr.com/v2/databases/database_id" \
    -X PUT \
    -H "Authorization: Bearer ${VULTR_API_KEY}" \
    -H "Content-Type: application/json" \
    --data '{
        "plan" : "vultr-dbaas-startup-cc-1-55-2"     
    }'

    Visit the Update Managed Database endpoint to view additional attributes to add to your request.

  1. List all database instances and note the database ID. For instance, d6ac2a3c-92ea-43ef-8185-71a23e58ad8c.

    console 
    $ vultr-cli database list --summarize

  2. Update the database plan by specifying a database ID and a new plan (For instance, vultr-dbaas-business-cc-1-55-2).

    console 
    $ vultr-cli database update database_id \
--plan vultr-dbaas-business-cc-1-55-2

    Run vultr-cli database update --help to view all options.

  1. Open your Terraform configuration and locate the Managed Database for MySQL resource.

  2. Update the plan argument with the new database plan ID.

    terraform 
    resource "vultr_database" "mysql" {
    label                   = "mysql-cluster-1"
    database_engine         = "mysql"
    database_engine_version = "8"
    region                  = "ewr"
    plan                    = "vultr-dbaas-business-cc-1-55-2" # Updated plan
}

  3. Apply the configuration and observe the following output:

    Apply complete! Resources: 0 added, 1 changed, 0 destroyed.
