Email is a critical service, and we understand that a forced maintenance window is disruptive: in some environments it is simply not an option. The breaking changes in `v0.16` are not cosmetic. Stalwart has been under continuous development for close to five years; in that time the feature set and the user base have both grown well beyond what the original configuration and management layer was designed for. The gap between what users need and what the old architecture can cleanly support has widened to the point where a redesign was unavoidable: and the redesign itself unlocks a long list of frequently-requested features that were simply not implementable under the previous model. The storage layer is untouched by all of this: emails, calendars, contacts, files, and every other piece of user data stay exactly where they are.

- A **zero-downtime migration utility**, and - A **zero-downtime migration utility** that moves data (accounts, mailboxes, calendars, contacts, files) from an existing (`v0.15.x` or below) deployment to a freshly-installed `v0.16.x` deployment one account at a time, while both servers are running.
- A **proxy** that sits in front of a running cluster and redirects users to the right node. - A **proxy** that sits in front of both deployments and routes each incoming connection to the server that currently owns that account. As accounts are migrated one by one, the proxy transparently shifts their traffic from the old deployment to the new one, so end users never notice a cutover.
When those tools are available, the instructions in this document will be superseded for most deployments. Everyone else can follow the manual steps below during a scheduled maintenance window. Together, these let operators migrate a live production deployment on an account-by-account basis with no scheduled maintenance window.

To avoid locking existing users out of their mail clients on the first login after the upgrade, `v0.16` **automatically appends the default domain** when a client authenticates with a bare username. Administrators running an **external directory** (LDAP, SQL, etc.), however, do need to update their directory filters to query by full email address rather than by bare account name; the old filters will no longer match. To avoid locking existing users out of their mail clients on the first login after the upgrade, `v0.16` **automatically appends the default domain** when a client authenticates with a bare username. Administrators running an **external directory** (LDAP, SQL, etc.), however, do need to update their directory filters to query by full email address rather than by bare account name; the old filters will no longer match.
**CalDAV, CardDAV, and WebDAV clients need one manual adjustment.** These protocols use the account name as part of the URL path (for example `/dav/cal/alice`), and because the account name is now a full email address, that path changes. The `@` character is reserved in URLs and must be encoded as `%40`, so the equivalent path in `v0.16` becomes `/dav/cal/alice%40example.com`. Authentication itself still works (the server accepts the bare username and appends the default domain, as described above), but calendar, contact, and file sync will stop working until each client is reconfigured to point at the new path. It is a good idea to notify users before the upgrade so that they can update their calendar and contacts accounts in Apple Calendar, Thunderbird, DAVx⁵, and similar clients.
Two reasons drove this requirement. The first is **support for multiple external directories simultaneously**: when account names are bare strings there is no reliable way to tell which directory owns a given username, whereas email addresses are naturally namespaced by domain and make that mapping unambiguous. The second, and more consequential, reason is the **PACC specification** ([draft-ietf-mailmaint-pacc](https://datatracker.ietf.org/doc/draft-ietf-mailmaint-pacc/)): the IETF's replacement for the fragmented collection of autoconfig / autodiscover / SRV-record mechanisms that mail clients use today to discover server settings. PACC expects login names shaped like email addresses; when they are not, the server has to reveal whether a given account exists just to disambiguate the login, which is exactly the privacy leak the spec is designed to prevent. Aligning account names with email addresses is what lets Stalwart implement PACC correctly. Two reasons drove this requirement.

PACC also brings OAuth into the autodiscovery flow, and because the draft originates from Apple, a correct PACC implementation is the path to supporting Apple Mail clients with OIDC and MFA: a long-standing user request that only becomes possible once this groundwork is in place.

Install Stalwart into standard FHS paths or under a custom prefix.
Options:
--fdb Install the FoundationDB build.
-h, --help Show this help.
With no PREFIX, Stalwart is installed under standard FHS paths:
binary /usr/local/bin/stalwart
config /etc/stalwart/config.json (created by the daemon on first run)
env /etc/stalwart/stalwart.env
logs /var/log/stalwart/
data /var/lib/stalwart/
