Upgrade PostgreSQL with Ksolves Experts

PostgreSQL 14 loses all community security coverage on November 12, 2026, with no further patches or fixes issued after that date. PostgreSQL 15 follows in November 2027. Every month of delay adds unpatched CVEs, compliance exposure under SOC 2, HIPAA, and PCI-DSS, and growing extended support fees from AWS and Google Cloud.

Ksolves delivers your PostgreSQL upgrade as a fixed-price engagement with a named engineering team, a written schema accuracy guarantee, and a firm timeline agreed before any work begins.

Why Upgrade PostgreSQL Now?

Six compounding risks that grow every day past the PG 14 end-of-life date of November 12, 2026

Unpatched Security Vulnerabilities

Every CVE identified after November 12, 2026, goes permanently unpatched in PG 14, leaving production databases with an open vulnerability backlog and no community fix path.

Compliance and Audit Exposure

SOC 2, PCI-DSS, and HIPAA audits treat EOL database software as a direct compliance gap, putting cyber insurance, certification renewals, and audit findings at risk.

Performance Gaps

PostgreSQL 16 delivers up to 300% COPY throughput improvement, query parallelism gains, and SIMD CPU acceleration for x86 and ARM. Every month on PG 14 is a month without these capabilities.

Missing Replication and Observability Features

Logical decoding from standbys, parallel apply for large transactions, and the pg_stat_io view are all PG 16 only. PG 14 and PG 15 have none of them.

Extension and Driver Compatibility Drift

Every deferred upgrade widens the compatibility gap across two major versions, making extensions, custom operators, and third-party integrations harder and riskier to migrate.

Growing Cloud Extended Support Costs

AWS RDS, Google Cloud SQL, and Azure all charge additional fees for EOL PostgreSQL instances. Every quarter of delay after November 2026 adds cost with no operational return.

Still running PostgreSQL 14 or 15?

Our certified engineers audit your cluster, flag every compatibility gap, and deliver a written upgrade plan at no cost.

Our PostgreSQL Upgrade Services

Every Ksolves PostgreSQL upgrade is scoped upfront, delivered by certified database engineers, and backed by a verified rollback strategy.

PostgreSQL 14 to 16 LTS Upgrade

PG 14 loses all security coverage on November 12, 2026. Ksolves runs schema and extension compatibility analysis, executes pg_upgrade or logical replication cutover, and validates query plan behavior before any production change is made.

PostgreSQL 15 to 16 LTS Upgrade

PG 15 reaches end-of-life in November 2027. Ksolves executes your migration now, eliminating future deadline pressure and delivering PG 16 performance improvements ahead of schedule.

Self-Hosted PostgreSQL Upgrade (Linux, Kubernetes, Bare Metal)

Ksolves manages pg_upgrade execution, extension rebuilds, replication topology reconstruction, SCRAM authentication validation, and standby resynchronisation across on-premises and self-hosted environments.

Managed Cloud PostgreSQL Upgrade (AWS RDS, Google Cloud SQL, Azure)

We handle pre-upgrade eligibility checks, resolve extension compatibility blockers, and validate every database post-restore across all three major cloud providers.

PostgreSQL CRM and Application Database Migration

Our experts audit application query compatibility against PG 16, validate ORM behavior post-upgrade, and coordinate cutover with application teams to prevent production regression.

Post-Upgrade Performance Tuning

Ksolves delivers 48 to 72 hours of post-upgrade monitoring covering autovacuum reconfiguration, connection pool revalidation, and a written handover with key metrics and next steps.

Our PostgreSQL Upgrade Migration Process

Every deliverable is backed by certified database engineers and a written schema accuracy guarantee.

1

6

Environment Audit (Days 1 to 3)

Cluster topology, installed extensions, replication configuration, and full schema inventory documented. Every custom function, stored procedure, and ORM mapping is assessed for PG 16 compatibility.

Compatibility Analysis (Days 3 to 5)

Every extension categorised as upgrade-compatible, requires a rebuild, or must be replaced. Output: written compatibility gap report ranked by blocking, recommended, and informational severity.

Upgrade Runbook (Days 5 to 7)

Step-by-step runbook covering pg_upgrade or logical replication sequence, extension reinstallation order, SCRAM authentication migration, and rollback triggers. Signed off with your team before staging begins.

Staging Validation (Days 7 to 14)

Full upgrade executed against staging. Row counts, query results, and replication throughput validated against PG 14 or PG 15 baselines. Production cutover requires a written sign-off from your team.

Production Cutover

Logical replication upgrades promote a validated PG 16 standby with seconds of switchover impact. pg_upgrade paths run during low-traffic windows with a tested rollback path maintained throughout.

Post-Upgrade Monitoring (48 to 72 Hours)

Vacuum activity, replication lag, connection pool health, and query plan behavior are monitored post-cutover. Engagement closes with a written handover covering what changed and key metrics to watch.

Frequently Asked Questions

End-to-end delivery of a production major version upgrade covering schema and extension compatibility analysis, pg_upgrade or logical replication execution, staging validation, production cutover, and post-upgrade monitoring. Ksolves handles every stage, so your team does not need to build that expertise in-house.

PostgreSQL 14 reaches end-of-life on November 12, 2026. With a typical engagement running 6 to 16 weeks, the planning window is closing. Starting now is the recommended approach.

Two paths: pg_upgrade for in-place binary upgrades, or logical replication for near-zero-downtime migration where a PG 16 cluster is built in parallel and promoted with a brief switchover. Ksolves selects the right method after a compatibility audit.

Yes. Ksolves builds and validates a PG 16 target cluster in parallel before any production change. Switchover takes seconds, with a tested rollback path maintained throughout.

PostgreSQL 15 reaches end-of-life in November 2027. No immediate emergency, but migrating now avoids future deadline pressure, eliminates extended support fees early, and delivers PG 16 improvements ahead of schedule.

Small databases: 2 to 4 weeks. Larger environments with complex schemas, extensions, and replication topologies: 6 to 16 weeks. Every engagement starts with a 5-day audit that produces a firm timeline before you commit.

Environment audit, compatibility gap report, upgrade runbook, staging validation, production cutover, and 48 to 72 hours of post-upgrade monitoring, with a named team, fixed price, and written schema accuracy guarantee agreed before work begins.

Self-hosted Linux, Kubernetes, and bare metal; Amazon RDS; Google Cloud SQL; Azure Database for PostgreSQL; and CRM or application database layers on PG 14.x or 15.x.
