Upgrading a major version of Kafka, PostgreSQL, or Kubernetes isn't just a configuration change — it's a project. DepKeep engineers have done it hundreds of times. We deliver compatibility analysis, runbooks, and hands-on cut-over support so your team can focus on the business, not the plumbing.
DepKeep engineers are on the keyboard with you — from the first compatibility assessment through to post-migration stability monitoring.
We map every breaking change between your current and target versions, cross-referenced against your application code, configuration, and third-party integrations.
Detailed, environment-specific runbooks covering every step — schema changes, configuration updates, dual-write patterns, and rollback procedures — reviewed by your team before execution.
We design blue-green or rolling upgrade strategies to eliminate maintenance windows — including dual-version compatibility layers where the target application requires it.
Every migration plan includes a tested rollback path. We validate rollback procedures in staging before any production change is attempted.
For databases and stateful services, we handle schema migrations, data format transformations, and post-migration integrity validation — with checksums and row-count verification.
For 30 days after cut-over, we monitor key metrics for regression — latency, error rates, query performance — and resolve any issues that surface from real production traffic.
We analyse breaking changes, deprecations, and compatibility requirements across your full dependency graph and application codebase.
We build environment-specific migration runbooks with every step, script, and decision point documented — reviewed and signed off by your engineering lead before execution.
The full migration is executed in a production-like staging environment. We validate performance, data integrity, and application compatibility before any production change.
We run the production migration alongside your team with a dedicated DepKeep engineer on the bridge — ready to execute the rollback plan at any sign of trouble.
Logical replication, extension compatibility, query plan changes, and pg_upgrade validation.
KRaft migration, consumer group protocol updates, and offset reset handling.
Module system migration, deprecated API removal, GC tuning for the new runtime.
Index mapping changes, security model update, and API compatibility layer removal.
Deprecated API groups, admission webhook updates, and node upgrade sequencing.
ACL changes, multi-exec behaviour, and Cluster topology rolling upgrade.
Teams running EOL software who need to migrate before LTS coverage ends or before regulatory deadlines force an emergency upgrade.
Migration projects that started internally but stalled — typically due to complexity, risk aversion, or competing engineering priorities — that need an expert injection to restart.
Teams lifting and shifting to a new cloud provider or managed service that requires a version upgrade alongside the infrastructure change.
Regulated organisations with hard deadlines to patch or upgrade specific components due to audit findings or regulatory guidance.
