Website Migration Between Servers Without Downtime

Website Migration Between Servers Without Downtime
Contents

    Moving to a new server usually comes with downtime, missing mail or half-broken sites. Done properly, the migration carries everything across with minimal interruption and keeps both mail and SEO intact.

    When you need it

    • slow or unreliable hosting;
    • moving to a stronger server as you grow;
    • consolidating several sites onto one server;
    • changing provider.

    What gets moved

    • the files of every site;
    • databases (consistent dumps);
    • mail with all mailboxes;
    • DNS, SSL and cron jobs.

    How downtime is avoided

    Data is synced to the new server in advance, then a final delta sync and a DNS switch with a lowered TTL. The old server stays live until DNS has fully propagated.

    The delicate parts

    • mail: mailboxes moved without losing messages;
    • SSL: certificates issued on the new server beforehand;
    • file permissions and paths inside configs;
    • cron and background jobs.

    Common questions

    Will there be downtime?

    Minimal — thanks to pre-syncing and the TTL drop.

    Will mail survive?

    Yes, mailboxes and messages are carried across.

    How many sites at once?

    Any number — from one to an entire server.
