DocFlow Upgrade Guide: Version 1.4.3

Scope

• This guide describes a safe, repeatable procedure to upgrade DocFlow to version 1.4.3.
• Because DocFlow can be deployed using different methods, the procedure provides method-specific steps and placeholders. Replace placeholders (for example, , , ) with values from your environment.
• If upgrading from a version earlier than 1.4.x, consult the vendor’s supported upgrade path and release notes before proceeding.

Pre‑upgrade Checklist

• Read the official DocFlow 1.4.3 release notes and verify any prerequisites, breaking changes, database migrations, configuration key changes, and deprecations.
• Confirm you have recent, restorable backups:
  • Database backup/snapshot
  • Persistent storage (attachments, uploads, etc.)
  • Configuration files and environment variables
  • Infrastructure as code (compose files, Helm values, manifests)
• Verify you have a tested rollback plan (including restoring database and reverting application version).
• Schedule a maintenance window if required by your change-management policy.
• Validate free disk space, resource headroom, and access to the artifact registry/package repository.

Change Control and Risk

• Expected downtime: varies by deployment and whether DB migrations are required. Zero-downtime may not be possible if schema changes are involved.
• Risk: medium. Ensure backups and a validated rollback.

Upgrade Steps

A. Docker Compose

1. Update the image tag to 1.4.3 in your docker-compose.yml for the DocFlow service. Example: image: /docflow:1.4.3
2. Pull the new image: docker compose pull
3. Apply the update: docker compose up -d
4. If the release notes require database/schema migration, execute the documented migration procedure for 1.4.3 (for example, a one-off container/job as instructed by the vendor).
5. Verify logs and health: docker compose logs -f
6. Confirm the running version via the application UI or version endpoint.

B. Docker (without Compose)

1. Pull the 1.4.3 image: docker pull /docflow:1.4.3
2. Stop and remove the existing container: docker stop && docker rm
3. Start a new container with the same volumes, networks, ports, and environment settings as before, but using the 1.4.3 tag. Example: docker run -d --name
   --env-file </path/to/env>
   -v </path/to/data>:/var/lib/docflow
   -p 80:80
   /docflow:1.4.3
4. Run any required 1.4.3 migration procedure as documented.
5. Verify logs: docker logs -f
6. Confirm the application version.

C. Kubernetes (Helm)

1. Update your values.yaml (or set on the command line) to use image.tag: "1.4.3".
2. Upgrade the release: helm upgrade --install
   -n
   -f values.yaml
   --set image.tag=1.4.3
3. Wait for rollout: kubectl rollout status deploy/ -n
4. If migrations are required, execute the documented migration Job or Helm hook for 1.4.3 and monitor to completion.
5. Validate readiness probes, logs, and application version.

D. Linux Service (tarball/binary installation)

1. Download the official 1.4.3 artifact from the vendor’s release repository and verify checksum/signature.
2. Stop the DocFlow service: sudo systemctl stop docflow
3. Back up the current installation directory and configuration.
4. Replace binaries/files with the 1.4.3 release per vendor instructions; preserve configuration and data directories.
5. Start the service: sudo systemctl start docflow
6. Execute any required migration procedure for 1.4.3.
7. Check service status and logs: sudo systemctl status docflow journalctl -u docflow -f
8. Confirm the application version.

E. OS Package Manager (adjust to your repository/package name)

• Use your distribution’s pinning/version selection to install exactly 1.4.3. The exact package name and version string can differ by repository.
• Example (APT; replace with your actual package name and version string): sudo apt-get update sudo apt-get install docflow=1.4.3-
• Example (YUM/DNF): sudo dnf install docflow-1.4.3-
• Restart the service and run any required migration steps.

Post‑upgrade Validation

• Application health: verify the UI loads, APIs respond, and background jobs are operating.
• Version: confirm DocFlow reports 1.4.3 in the UI, CLI, or version endpoint.
• Data integrity: spot-check records, attachments, and search/index features.
• Logs and metrics: monitor error rates, latencies, and resource utilization for anomalies.
• Integrations: test key inbound/outbound integrations, webhooks, and authentication (SSO, OAuth, etc.).
• Clear application caches if recommended by the release notes.

Rollback Procedure

• If a critical issue occurs:
  • Application: revert to the previously known-good version.
    • Docker Compose: change image tag back and run docker compose up -d.
    • Docker: start a container with the prior tag.
    • Helm: helm rollback .
    • System service/package: reinstall the previous version or restore the previous binaries.
  • Database: if schema migrations were applied and are not compatible with the previous version, restore the database from the pre-upgrade backup/snapshot.
  • Validate service health and version after rollback.

Audit and Documentation

• Record: start/end times, versions before/after, commands executed, migrations performed, and validation results.
• Capture logs of the upgrade window and store alongside change records.

Notes

• Always prefer pinned image digests (for example, /docflow@sha256:) in production to ensure supply-chain integrity.
• If any step in this guide conflicts with the official DocFlow 1.4.3 release notes, follow the vendor documentation.

If you share your deployment method (Docker/Compose, Kubernetes/Helm, package manager, or binary) and current version, I can provide an exact, command-level runbook tailored to your environment.
