Upgrade Operations

This runbook defines the minimum upgrade path for LumiBase deployments on Cloudflare-hosted and Docker self-hosted environments. Treat every upgrade as a change-management event: choose an explicit version, back up data, run migrations intentionally, verify the running app, and keep a bounded rollback plan.

Versioning policy: fixed-version

LumiBase uses a fixed-version operations policy for production upgrades.

Pin production deployments to an explicit release channel or immutable version instead of tracking an unreviewed moving target.
Record the current app version, target app version, migration identifier, Docker image digest when applicable, and deploy timestamp in the change ticket.
Promote versions through environments in order: development, staging, then production.
Avoid mixing app binaries and database schema versions outside the compatibility window documented by each release note.

Release channels

Supported release channels are:

Channel	Meaning	Recommended use
`edge`	Fast-moving preview channel built from the newest accepted changes.	Development and early integration only.
`latest`	Current generally recommended release.	Small non-critical deployments that accept automatic patch adoption after review.
`X.Y`	Minor release line, for example `1.4`.	Production fleets that want patch updates inside one minor line.
`X.Y.Z`	Fully fixed patch release, for example `1.4.2`.	Production environments that require reproducible deploys and explicit change approval.

Prefer X.Y.Z for regulated or high-availability production systems. Use X.Y only when the team has an automated staging validation gate for new patch releases.

Cloudflare-hosted upgrade flow

Read the target release notes and identify required environment variable, binding, queue, R2, KV, Hyperdrive, D1/Postgres, and migration changes.
Snapshot configuration and secrets metadata without exposing secret values.
Run the backup checklist.
Deploy the target CMS Worker version to staging first.
Run the migration checklist against staging.

Verify the app version endpoint:

bash

curl -fsS https://<cms-host>/api/v1/system/version

Smoke test authentication, Studio access, collection reads/writes, file operations, flows/webhooks, and realtime if enabled.
Promote the same fixed release to production using the approved Cloudflare deployment process.
Re-run the version check and production smoke tests.
Keep the previous app deployment available until the rollback window closes.

Docker self-host upgrade flow

Review the target release notes and confirm that your compose file, environment variables, volumes, and database version satisfy the target release requirements.
Run the backup checklist.
Pull the target CMS image:
bash
```
docker compose pull cms
```
Start only the CMS service on the new image:
bash
```
docker compose up -d cms
```
Run the migration checklist.
Verify the app version endpoint from the host or load balancer:
bash
```
curl -fsS http://localhost:1989/api/v1/system/version
```

Check container health and logs:

bash

docker compose ps cms
docker compose logs --tail=200 cms

Smoke test authentication, Studio access, collection reads/writes, file operations, flows/webhooks, and realtime if enabled.
Keep the previous image tag or digest available locally until the rollback window closes.

Backup checklist

Before any upgrade, capture enough state to restore service outside the application rollback path:

Database logical backup, plus a restore test for production-critical datasets.
Object storage backup or versioned snapshot for uploaded files and generated assets.
Exported LumiBase configuration for collections, fields, roles, policies, permissions, flows, webhooks, and extensions.
Environment variable inventory and platform binding inventory.
Current app version and target app version.
Current Docker image tag and digest for self-hosted installs.
Current Cloudflare Worker deployment ID for Cloudflare-hosted installs.
Migration history table contents and pending migration list.
Recent application logs and metrics baseline.

Migration checklist

Run migrations deliberately and verify both schema and application behavior:

Read release notes for destructive, long-running, or manual migrations.
Confirm database backups completed and can be restored.
Confirm no unexpected pending migrations exist before starting.
Run migrations in staging before production.
For production, schedule a maintenance window if the migration changes large tables, indexes, constraints, permissions, or tenant-scoped data.
Apply migrations with the same application version that will serve traffic.
Verify migration history after completion.
Smoke test core reads and writes for at least one representative site tenant.
Keep a record of migration IDs applied during the upgrade.

Upgrading to 1.0

1.0.0 is the first release that carries a semver stability guarantee (see the versioning policy in the README). Because it freezes the public surface, the path onto it depends on the version you start from. Read this section end to end before you begin — some source versions upgrade in place, others require an intermediate stop, and one range cannot be migrated forward at all.

Supported upgrade sources

From	Path to 1.0.0	Notes
`0.18.x` – `0.21.x`	Direct.	Table prefix and RBAC model already match 1.0. Run the migration checklist; no manual data step.
`0.6.x` – `0.17.x`	Direct, with the RBAC backfill below.	Schema migrations are cumulative and idempotent. The one manual verification is the role→policy backfill (see RBAC role→policy backfill).
Before `0.17.0` (unprefixed tables)	Not supported as an in-place upgrade.	The `0.17.x` table-prefix change is fresh-install-only. Instances created before `0.17.0` must export their data (collections, items, files, roles/policies/permissions, flows, webhooks) and re-import into a fresh `1.0.0` install. There is no forward migration for the unprefixed schema.
Before `0.6.0`	Via an intermediate `0.17.x` – `0.21.x` release first.	Upgrade to a recent `0.x` (which applies the RBAC backfill and any prefix handling), verify, then upgrade to `1.0.0`. Do not skip directly.

Determine your current version from /api/v1/system/version before choosing a row.

RBAC role→policy backfill

1.0.0 treats policies as the source of truth for admin_access and app_access (plus enforce_tfa, IP guards, and time windows). Instances that predate the policy model stored these as flags on roles. During the compatibility window PermissionService still reads role flags OR active policy flags, so access does not break on upgrade — but before 1.0.0 you should materialize the legacy role flags into policy rows so the policy layer alone is authoritative.

The backfill is idempotent and does not mutate role flags (they remain intact as the rollback anchor). For each role where admin_access or app_access is true it creates one flag-only policy — key legacy_role_flags_<role_key>, name Legacy role flags: <role name>, copying the exact flag values, with enforce_tfa=false, empty IP guards, and null time windows — and attaches it to the role via role_policies. Full contract and SQL: Role Flag to Policy Flag Migration.

Run it against staging first, then verify. The post-check must return zero rows — every role that carries a legacy flag must have a matching policy:

sql

SELECT r.id, r.site_id, r.name, r.admin_access, r.app_access
FROM lumibase_roles r
WHERE (r.admin_access = true OR r.app_access = true)
AND NOT EXISTS (
  SELECT 1
  FROM lumibase_role_policies rp
  JOIN lumibase_policies p ON p.id = rp.policy_id
  WHERE rp.role_id = r.id
    AND p.admin_access = r.admin_access
    AND p.app_access = r.app_access
);

Then confirm effective access is unchanged: a legacy admin role is still admin, a legacy app-only role can still enter Studio, and a role without app access still cannot. This verification has been run against the 1.0 release fixtures and returns clean. Role flag columns stay in place through 1.0 for rollback; they are only scheduled to drop in a later release after LUMIBASE_RBAC_LEGACY_ROLE_FLAGS=false has shipped and been verified.

Rollback from 1.0

Application: roll back to the previous 0.21.x deployment per rollback app. 1.0.0 adds no destructive schema change over 0.21.x, so the prior app version remains compatible with the 1.0 database.
RBAC backfill: it is separately reversible during the compatibility window — delete the legacy_role_flags_% policies and their role_policies rows (role flags are untouched, so access is preserved). See §6 Rollback.
Pre-0.17 re-import path: there is no rollback to the old unprefixed schema; keep the source instance running read-only until the 1.0 install is verified.

Rollback app

Application rollback means routing traffic back to the previous app deployment while keeping the database at its current post-upgrade state unless a separate database restore is approved.

Cloudflare-hosted: roll back to the previous Worker deployment or redeploy the previous fixed version.
Docker self-host: start the previous fixed image tag or digest.
After rollback, verify /api/v1/system/version and run smoke tests.
Confirm the previous app version is compatible with the current database schema before keeping it in service.

Rollback Docker image

Use immutable tags or digests when possible:

bash

# Example: pin the compose file or override to the previous image first, then restart cms.
docker compose up -d cms
curl -fsS http://localhost:1989/api/v1/system/version

If the previous image is not available locally, pull the exact previous tag or digest before restarting:

bash

docker compose pull cms
docker compose up -d cms

Do not roll back to latest blindly; update the compose image reference to the intended X.Y.Z tag or digest first.

Rollback database limits

Database rollback is limited and higher risk than application rollback.

LumiBase does not assume every migration is reversible.
Downgrade migrations may not exist for destructive schema changes, data rewrites, backfills, or permission model changes.
Restoring a database backup can discard writes created after the backup timestamp.
Restoring only the database without matching object storage and configuration exports can create inconsistent state.
Database restore must be treated as a disaster-recovery action with explicit approval, a write freeze, and a post-restore consistency check.
Prefer forward fixes when the upgraded database is healthy and only application behavior needs correction.
