jcoffey-dev bfea4a5467 Rewrite the README for inbuxa-migrate
The README now says what the tool is in the suite's plain voice: the
archive in the middle, convergent reruns, --dry-run, the archive as a
backup, the sources it reads (Stalwart among the JMAP ones), the
INBUXA_MIGRATE_* credential variables, installing from the Gitea release
with SHA256SUMS, building and testing, and the license with the lineage
line. Upstream's logo, badges and install channels are gone.

The full command and flag reference moves to docs/usage.md, with the
renamed binary and variables. The CHANGELOG gains a section for this first
release, above upstream's history.

inbuxa-migrate

Note

Development happens on git.coffeylabs.org/inbuxa/inbuxa-migrate; the copy on GitHub is a read-only mirror. Report issues at git.coffeylabs.org/inbuxa/inbuxa-migrate/issues, and join discussions at community.coffeylabs.org.

One program that moves an account into inbuxa: its mail, calendars, contacts, identities, Sieve scripts and files.

inbuxa-migrate import imap … alice.sqlite    an account into an archive
inbuxa-migrate inspect alice.sqlite          what landed
inbuxa-migrate export … alice.sqlite         the archive into inbuxa

Between the two sides sits an archive: one SQLite file holding one account. import fills it from the old server; export writes it into the new one. Import and export never talk to each other, only to the archive, so the old server can be gone before the new one exists.

Both commands converge. An interrupted run picks up where it stopped, and a later import into the same archive adds what arrived since. Every command takes --dry-run and then only reports the plan. inspect reads an archive and changes nothing.

The archive is also a backup. Import on a schedule, keep the file, and restore it later with export. An archive remembers which account filled it and refuses a different one unless told otherwise.

Export speaks JMAP only. It writes into inbuxa, or into any JMAP server that advertises the types being written. The full command reference is in docs/usage.md.

Sources

  • JMAP -- any JMAP account, including an inbuxa or Stalwart server.
  • IMAP -- mail only. Folders are chosen by name or by pattern.
  • CalDAV, CardDAV -- calendars and events, address books and contacts.
  • WebDAV -- a plain file collection, kept as a file tree.
  • ManageSieve -- Sieve scripts only, with the active one recorded.
  • Maildir -- a local Maildir++ tree. No network.
  • Google Takeout -- the .mbox, .ics and .vcf files in a Takeout export, or in any directory tree laid out that way.
  • Exchange Server -- an on-premises mailbox, through EWS.
  • Exchange Online -- through Microsoft Graph. EWS is being retired in Exchange Online: blocked from 1 October 2026 unless an administrator allows the client, and switched off on 1 April 2027. Public folders are only reachable through EWS.

Credentials

Secrets are read from the environment, or asked for at a prompt:

INBUXA_MIGRATE_PASSWORD               a password for --auth-basic
INBUXA_MIGRATE_TOKEN                  a bearer token for --auth-bearer
INBUXA_MIGRATE_EWS_CLIENT_SECRET      the OAuth client secret for app-only EWS
INBUXA_MIGRATE_GRAPH_TOKEN            a Microsoft Graph access token

The command line takes them too, but a secret there ends up in the shell's history and in the process list. Use the environment or the prompt.

Installing

Linux, on amd64 or arm64. Each release carries one archive per architecture and a SHA256SUMS file:

base=https://git.coffeylabs.org/inbuxa/inbuxa-migrate/releases/latest/download
curl -fLO "$base/inbuxa-migrate-linux-amd64.tar.gz"
curl -fLO "$base/SHA256SUMS"
sha256sum --check --ignore-missing SHA256SUMS
tar -xzf inbuxa-migrate-linux-amd64.tar.gz
./inbuxa-migrate --version

On arm64, fetch inbuxa-migrate-linux-arm64.tar.gz instead. The binary is the whole program; put it anywhere on the path.

Building and testing

cargo build --release          the binary is target/release/inbuxa-migrate
cargo test                     the default suite

The default suite needs no network and no Docker. Unit tests and scripted mocks stand in for JMAP, DAV, EWS and Graph servers.

The live tests are marked #[ignore]. Each boots a throwaway container -- Stalwart, Dovecot, Cyrus, Radicale, Baikal or Apache mod_dav -- so they need a working Docker daemon. Run them one binary at a time, and always with one test thread:

cargo test --test sync_jmap -- --ignored --test-threads=1
cargo test --test integration_dovecot -- --ignored --test-threads=1

The tests in a binary share one container and one disposable domain, so a second thread would trip over the first. docs/usage.md lists every live test binary.
