upgrading-cluster-version

A guide to upgrading the software version of a CockroachDB cluster. The process ranges from replacing binaries on self-hosted nodes to starting upgrades in CockroachDB Cloud, while some plans upgrade automatically.

In plain words
What is it for?
Use it to plan or perform upgrades, configure patch policies or release channels, verify the result, and manage the finalization step for self-hosted upgrades.
Why use it?
It helps you choose a safe upgrade path based on the current version and deployment type, and shows how to verify completion or decide whether to finalize or roll back.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade B, and why

upgrading-cluster-version scanned grade B with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

A mod that escalates privileges can change anything on the machine, not only the project.

Upgrading Cluster Version

Guides CockroachDB version upgrades end-to-end. Before providing procedures, this skill gathers deployment context to deliver only the steps relevant to the operator's tier.

When to Use This Skill

  • Planning or executing a version upgrade (Self-Hosted)
  • Initiating a major version upgrade via Cloud Console (Advanced, BYOC)
  • Configuring how patches are applied (Advanced, BYOC)
  • Verifying upgrade completion (all tiers)
  • Deciding whether to finalize or roll back (Self-Hosted)

For pre-upgrade health check: Use reviewing-cluster-health. For node drain during Self-Hosted upgrade: Use performing-cluster-maintenance. For maintenance window configuration: Use performing-cluster-maintenance.


Step 1: Gather Context

Required Context

Question Options Why It Matters
Deployment tier? Self-Hosted, Advanced, BYOC, Standard, Basic Completely different upgrade procedures per tier
Current version? e.g., v24.2.5 Validates upgrade path and compatibility

Additional Context (by tier)

If Self-Hosted:

Question Options Why It Matters
Upgrade type? Major (e.g., 24.2→24.3), Patch (e.g., 24.2.5→24.2.8) Major requires finalization; patches do not
Target version? e.g., v24.3.1 Confirms version is available and sequential
Deployment platform? Bare metal, VMs, Kubernetes (Operator/Helm/manual) Changes binary replacement and restart procedure
Process manager? systemd, manual, container orchestrator Changes stop/start commands
Node count? Number Affects upgrade sequencing

If Advanced or BYOC:

Question Options Why It Matters
Upgrade type? Major version, Patch Major requires Console initiation; patches use maintenance windows
Cloud provider? (BYOC only) AWS, GCP, Azure For infrastructure-level monitoring during upgrade
Release channel? Regular, Innovation Innovation gives latest features, shorter support window

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
