Migrating to DatAdmin Personal: Step-by-Step ChecklistMigrating to DatAdmin Personal can simplify local database management, speed up development workflows, and give you a lightweight, privacy-friendly environment for working with data. This step-by-step checklist walks you through planning, preparing, executing, and validating a migration so you can move with confidence and minimize downtime or data loss.
Before you start: key decisions and inventory
- Decide migration scope. Choose which databases, tables, apps, and scripts will move to DatAdmin Personal. Will you migrate everything or only selected projects?
- Inventory current environment. List DB engines (MySQL, PostgreSQL, SQLite, SQL Server, etc.), versions, sizes, extensions, stored procedures, scheduled jobs, and integration points (backups, apps, CI pipelines).
- Check compatibility. Confirm DatAdmin Personal supports your database types and features you rely on (collations, extensions, triggers, procedural languages).
- Define success criteria. Examples: all tables and rows migrated, queries return identical results, apps run without config changes, backups scheduled and tested.
Step 1 — Prepare source systems
- Backup everything. Create full backups of each database and copy files to a safe location.
- Note users and permissions. Export user-role mappings and credentials where applicable.
- Freeze schema changes. Coordinate with team to hold DDL changes during migration windows.
- Capture configuration. Export database settings, connection strings, and environment variables used by apps.
Step 2 — Set up DatAdmin Personal
- Install DatAdmin Personal on target machine(s) and verify the version.
- Configure storage and disk layout. Ensure adequate free space for data and backups.
- Configure network and firewall rules if DatAdmin needs to accept remote connections.
- Create service accounts and set permissions for local access and scheduled tasks.
Step 3 — Schema migration
- Export schema from source. Use native tools (pg_dump –schema-only, mysqldump –no-data, or similar) or DatAdmin’s import utility.
- Review schema for incompatible elements. Look for engine-specific features (e.g., Postgres extensions, MyISAM-specific behavior) and plan replacements or workarounds.
- Apply schema to DatAdmin. Import the schema and check for errors.
- Validate schema. Confirm tables, indexes, constraints, triggers, and stored procedures exist and compile where applicable.
Step 4 — Data migration
- Choose migration method:
- Bulk export/import (dump files).
- Replication or live sync for minimal downtime.
- CSV exports for smaller tables.
- Migrate large tables in chunks if needed to avoid resource spikes.
- Preserve identity columns and sequences. Ensure auto-increment/sequence values are set correctly after import.
- Verify row counts and checksums. Compare source vs target counts and run sample queries to validate content.
Step 5 — Migrate users, roles, and permissions
- Recreate database users and roles on DatAdmin Personal.
- Apply permissions and role memberships.
- Test authentication for apps and users; update connection strings if credentials changed.
Step 6 — Migrate routines, jobs, and integrations
- Recreate scheduled jobs and maintenance tasks in DatAdmin Personal’s scheduler or use OS-level cron/tasks.
- Re-deploy stored procedures, functions, and triggers; run unit tests if available.
- Reconfigure integrations (backups, ETL, monitoring, CI/CD). Update endpoints and credentials.
- Test any external systems that rely on the database (APIs, apps, reporting tools).
Step 7 — Application cutover and configuration
- Update application connection strings to point to DatAdmin Personal.
- If necessary, adjust connection pool, timeout, and driver settings for performance.
- Run smoke tests covering critical application flows.
- Perform a staged rollout if possible (canary users, feature flags) to limit risk.
Step 8 — Validation and testing
- Functional tests: queries, writes, transactions, and stored procedures.
- Performance tests: measure query latency and throughput against your benchmarks.
- Consistency checks: row counts, checksums, and referential integrity.
- Edge-case tests: concurrent writes, error handling, and failover behavior.
Step 9 — Backups and disaster recovery
- Implement a backup strategy: full, differential/incremental, and transaction log backups as supported.
- Automate backup retention and purging policies.
- Test restore procedures regularly by performing full restores to a test environment.
- Document recovery steps and contact points.
Step 10 — Monitoring, maintenance, and tuning
- Set up monitoring for disk space, CPU, memory, connections, and query performance.
- Configure alerts for critical thresholds (low disk, long-running queries, failed backups).
- Schedule routine maintenance: vacuuming/optimization, index rebuilding, statistics updates.
- Review and tune indexes and queries based on new workload patterns.
Rollback plan
- Keep the source system available and in read-only or paused state until final confirmation.
- Maintain synchronization (replication or incremental dumps) during testing to minimize data drift.
- If issues arise, revert application connections to the original database and investigate.
Post-migration checklist
- Confirm all apps and users are functioning normally.
- Archive migration logs, scripts, and configuration snapshots.
- Update documentation with new connection strings, backup locations, and runbooks.
- Hold a post-mortem to capture lessons learned and improvement areas.
Common pitfalls and quick tips
- Don’t forget to migrate collation and encoding settings — mismatches can break queries and sorting.
- Watch out for engine-specific SQL that may need rewriting.
- Test large-object (BLOB) transfers separately — they often cause problems in bulk moves.
- Plan for disk space overhead during import; compressed backups expand when restored.
