RDS MySQL 8.0 is
end of life.
Don't let AWS upgrade your database for you.

Oracle ended MySQL 8.0 Premier Support in April 2026. AWS will auto-upgrade your RDS instances on July 31, 2026 — with no compatibility testing and no rollback. Mydbops plans and executes your 8.0 → 8.4 LTS migration with zero downtime, full validation, and post-migration hypercare from an AWS Advanced Tier Services Partner with AWS Certified DBAs — ISO 27001 & PCI-DSS certified.

The Risk of Inaction

Your database is days from a forced upgrade — or a permanent security gap.

Every day past April 2026, MySQL 8.0 accumulates permanently unpatched CVEs. Every day past July 31, 2026, AWS either charges Extended Support fees or executes an untested upgrade in a window you didn't plan.

AWS Auto-Upgrade Deadline

00Days

00Hrs

00Min

00Sec

Until July 31, 2026 — the date AWS begins auto-upgrading unmanaged RDS MySQL 8.0 instances, with no compatibility testing and no rollback path.

What AWS will do on August 1, 2026 — if you haven't migrated

⚡

Force a major version upgradeAWS triggers MySQL 8.0 → 8.4 during a scheduled maintenance window — on AWS's timeline, not yours.

🚫

Zero compatibility testingNo stored procedure validation, no schema compatibility checks, no application regression testing before the upgrade executes.

🔒

No rollback pathOnce the major version upgrade completes, there is no supported rollback to MySQL 8.0. You're committed to 8.4 — ready or not.

💸

Extended Support fees activateIf you opt out, AWS Extended Support billing starts — per-vCPU-hour charges that escalate annually per database.

run_compatibility_check --target=mysql-8.4 --env=production

Critical

mysql_native_password disabled by default

Every user provisioned with this auth plugin fails to authenticate the moment MySQL 8.4 starts. Silent auth breakage in production with no warning.

High Risk

Strict Foreign Key Enforcement

MySQL 8.4 enables restrict_fk_on_non_standard_key by default. FKs referencing non-unique indexes now fail — breaking schemas that passed silently in 8.0.

High Risk

Composite Primary Key FK Violation

MySQL 8.4 forbids FK references to partial composite primary keys unless a separate UNIQUE constraint exists. Existing schema designs may be instantly non-functional.

High Risk

GTID Replication Behavior Changes

MySQL 8.4 introduces new GTID tags that improve stability but require topology-aware migration. Replication chains built on 8.0 assumptions need reconfiguration.

Medium

Removed Deprecated Functions

Stored procedures, triggers, and views using deprecated 8.0 syntax fail silently or throw errors. No compiler warning — discovery only happens at runtime.

Medium

Optimizer & SQL Mode Changes

Stricter default SQL mode and updated query planner can cause previously-passing queries to fail or generate execution plan regressions under production load.

Compliance Failures

EOL MySQL 8.0 fails PCI-DSS Req 6.3, ISO 27001 A.12.6, and SOC 2 CC7.1 at once — an unresolvable audit finding until you upgrade.

Escalating AWS Costs

A 4-vCPU Multi-AZ RDS instance can exceed $1,300/month in Year 3 Extended Support fees. Per database. Scaling with your fleet — indefinitely.

Cyber Insurance Exposure

Most policies now require patched, supported stacks. Running EOL MySQL 8.0 post-April 2026 creates coverage disputes and may void claims.

Why Mydbops — Not DIY or AWS Auto-Upgrade

The difference between a managed migration and an incident report.

AWS auto-upgrades perform zero compatibility testing. Internal teams lack the 8.4-specific tooling and replication topology experience. Here's what that gap costs you in practice.

DIY / AWS Auto-Upgrade

✗

No compatibility assessmentAWS auto-upgrade skips schema audit entirely. DIY teams rarely have the 8.4-specific tooling to catch all breaking changes.

✗

No staging validationApplication regression testing against a MySQL 8.4 mirror is skipped. Breaking changes surface in production.

Mydbops Managed Recommended

✓

Full 3–5 day compatibility auditEvery schema, stored procedure, trigger, FK reference, and mysql_native_password user is audited before a single production change.

✓

Full staging migration + regression testsProduction mirror built in staging. Regression suites run. Query plan benchmarks compared before production is touched.

DIY / AWS Auto-Upgrade

✗

No rollback pathAWS provides no rollback to 8.0 once the upgrade completes. Self-managed rollbacks need pre-built reverse replication rarely set up in advance.

✗

Unknown downtime — can be hoursAWS maintenance windows don't guarantee short cutovers. Complex schemas can cause multi-hour outages with no warning.

✗

AWS sets the date — you don'tMiss the July 31 deadline and AWS decides when your database gets upgraded. You lose control of timing entirely.

Mydbops Managed Recommended

✓

Tested rollback plan — every migrationReverse replication configured before cutover. Rollback criteria documented. The decision can be executed in minutes, not hours.

✓

<10 minutes — proven at 180+ server scaleBlue/green or CDC-based AWS DMS migration. Swiggy: 180+ servers, under 10 minutes downtime. Measured and documented.

✓

You control the migration timelineCutover scheduled during your lowest-traffic window. You approve every stage before execution proceeds.

DIY / AWS Auto-Upgrade

✗

No post-migration supportAWS support ends at cutover. Internal teams resume normal capacity immediately. No dedicated DBA for post-go-live regressions.

✗

No compliance documentationNo audit-ready evidence package. PCI-DSS Req 6.3 and ISO 27001 findings stay open until you produce documentation you don't have.

Mydbops Managed Recommended

✓

2–4 weeks dedicated hypercareA senior Mydbops DBA stays on standby with full incident SLA active. GenAI observability flags regressions before users notice.

✓

Common Questions

MySQL 8.0 EOL upgrade questions, answered

Oracle ended Premier Support for MySQL 8.0 in April 2026, halting all security patches and CVE backports. Any vulnerability discovered after this date remains permanently unpatched in 8.0. Organizations running MySQL 8.0 in production now carry active, unresolvable security exposure until they upgrade.

AWS will automatically upgrade your RDS MySQL 8.0 instances to MySQL 8.4 on July 31, 2026. This auto-upgrade performs no application compatibility testing, may silently break stored procedures or queries using deprecated syntax, and provides no rollback path. A planned, tested migration is significantly safer.

Mydbops uses a blue/green deployment or CDC-based live migration via AWS DMS. Your MySQL 8.0 environment stays live while the 8.4 target is built and fully validated. Traffic switches only after regression testing passes, typically achieving under 10 minutes of production downtime on large multi-server fleets.

MySQL 8.4 removes deprecated functions, changes default SQL modes, and updates optimizer behavior. Stored procedures using removed syntax will fail silently. Mydbops runs a full pre-migration compatibility assessment covering schemas, queries, stored procedures, triggers, and replication topology before any production change begins.

Post upgrading to 8.4 version, there has been some improvement in query execution & there are few cases where we have observed reduction in CPU utilisation as well. The improvement in performance directly relates to the improved optimiser on MySQL 8.4 versions.

Yes. MySQL 8.4 is Oracle's designated LTS (Long-Term Support) release, supported through 2032. It delivers improved GTID replication stability, InnoDB performance improvements, and enhanced optimizer reliability. For AWS RDS users needing multi-year stability without forced upgrades, MySQL 8.4 LTS is the correct target.

The full process — assessment, staging migration, validation, and production cutover — typically takes 3–4 weeks for most environments. Simple single-instance setups can complete faster. Complex multi-server fleets with custom replication topologies may require additional time. Mydbops provides a firm timeline after the initial discovery call.

Let's Talk
