mysqlcc (formerly MySQL Control Center): A Complete Overview

Migrating from MySQL Control Center to mysqlcc: Step‑by‑Step Guide

Summary

A concise, practical migration plan to move from MySQL Control Center (legacy) to mysqlcc with minimal downtime and preserved configuration.

Preconditions (assumed)

• You have admin access to servers and config files.
• Backups of databases and MySQL Control Center configuration exist.
• Target environment meets mysqlcc system requirements (same OS family, required Python/Java runtime if applicable).

Steps

1. Backup everything

   • Dump all databases: mysqldump –all-databases > all_databases.sql
   • Export MySQL Control Center config files and user data (usually in /etc/mysqlcc or ~/.mysqlcc)
   • Snapshot or backup server VMs if available

2. Inventory current setup

   • Note versions of MySQL server, connectors, and MySQL Control Center.
   • Record scheduled jobs, users, ACLs, custom scripts, and monitored hosts.

3. Read mysqlcc release notes

   • Check breaking changes, removed features, and migration tips in mysqlcc docs.

4. Install mysqlcc in a staging environment

   • Follow mysqlcc installer or package instructions for your platform.
   • Install required dependencies and connectors matching your MySQL server version.

5. Import configuration and credentials

   • Translate or copy existing config files into mysqlcc format. If formats differ, map settings: hosts, ports, credentials, monitoring intervals, alerts, and custom scripts.
   • Recreate users and permissions in mysqlcc using secure credential storage.

6. Migrate scheduled tasks and automation

   • Recreate scheduled jobs (backups, maintenance, replication checks) in mysqlcc scheduler.
   • Verify paths and environment variables for scripts.

7. Connect and validate monitored servers

   • Add each MySQL instance to mysqlcc.
   • Verify connectivity, metrics collection, and user access.
   • Run health checks and compare metrics with legacy tool outputs.

8. Test functionality

   • Run a full feature validation: queries, backups, restores (restore test), failover procedures, alerts, and reporting.
   • Confirm monitoring thresholds and notification channels (email, webhook, etc.) work.

9. Data migration for historical metrics (optional)

   • If you need historical metrics from MySQL Control Center, export them (CSV/JSON/SQL) and import into mysqlcc’s storage if supported—otherwise archive legacy metrics for reference.

10. Cutover plan

• Schedule a maintenance window.
• Put legacy MySQL Control Center in read-only or disable new writes.
• Switch DNS/shortcuts and update documentation to point to mysqlcc.
• Monitor closely for several hours to ensure stability.

11. Rollback plan

• Keep legacy backups and the old Control Center available until you verify mysqlcc is stable.
• Document rollback steps (restore configs, re-enable services).

12. Post-migration tasks

• Decommission old MySQL Control Center after verifying no dependencies remain.
• Update runbooks, access lists, and alert contacts.
• Train team on mysqlcc features and differences.

Quick checklist (before leaving)

• Database dumps completed
• Configs backed up
• Staging validation passed
• Scheduled jobs recreated
• Monitoring and alerts verified
• Cutover performed and observed
• Rollback plan documented
