If you’re running email on an IMAP server and starting to feel the limits – unreliable performance and clunky webmail – it’s time to move to a modern email platform. For many UK SMEs, the best choice is Gmail for Google Workspace.


With over 15 years of Google Workspace migration expertise, we’ve put together this quick, practical guide to help your business switch from IMAP to Gmail.

Why move from IMAP to Google Workspace?

IMAP email – whether hosted in your office or with a generic provider bundled with cPanel – was designed in a very different era. It handles basic email, but lacks the collaboration, reliability and integrated tools that modern businesses expect.

UK SMEs often move from IMAP to Google Workspace to:

  • Replace ageing or hard-to-manage mail servers with a fully managed, cloud-based solution.
  • Improve reliability and uptime, cutting the risk of email outages.
  • Give staff modern tools like Gmail, Google Calendar, Google Drive and Google Meet in one integrated platform.
  • Strengthen security with multi-factor authentication, advanced spam and malware protection, and robust admin controls.

Instead of just “fixing the email again”, you can step up to a platform built for always-on, collaborative working.

Step 1: Understand your current IMAP environment

Before planning an IMAP to Google Workspace migration, you need a clear picture of what you’re running today. Even a simple IMAP setup can hide complexity.

Start by identifying:

  • Your current mail server: Is it on-premise (for example, a Linux mail server in your office) or hosted by a third-party provider like HostGator or Hostinger?
  • Mailboxes and aliases: How many user mailboxes, shared mailboxes and forwarding addresses exist?
  • Storage and backups: Where is email data stored, how much space is in use and how is it backed up?
  • Other services: Are you also using the server for things like mailing lists, webmail interfaces such as Roundcube, Horde, or SquirrelMail, or basic calendars?

Gathering this information gives you a solid baseline. It helps you estimate the size of your migration and highlights any special cases – like old shared accounts – that may need extra attention.

Step 2: Plan your new structure in Google Workspace

Google Workspace doesn’t just host email; it provides a full productivity suite. As an IT manager, you need to decide how your current IMAP mailboxes will map into this new environment.

Key planning questions include:

  • User accounts: Which IMAP mailboxes will become individual Google Workspace user accounts?
  • Shared mailboxes: Which shared or generic addresses (like info@ or support@) will become group aliases or collaborative inboxes in Gmail?
  • Calendars: If you currently use basic calendar tools or none at all, how will you introduce Google Calendar for team scheduling?
  • Storage and collaboration: How will you use Google Drive and shared drives to replace any ad hoc file-sharing methods tied to your IMAP setup?

This design step ensures that when users log into Google Workspace for the first time, their accounts, aliases and basic workflows already make sense.

Step 3: Choose a sensible IMAP migration strategy

IMAP to Google Workspace migration is usually simpler than moving from a full Microsoft 365 environment, but it still pays to choose a strategy rather than migrate piecemeal.

Things to consider:

All-at-once vs phased
Do you move all mailboxes at once, or start with a pilot group before migrating everyone else?

Email-only vs wider rollout
Are you just moving email, or introducing calendars, Drive and Meet from day one?

Cutover day
When will you switch DNS and routing so that new email flows into Gmail instead of your IMAP server?

Many small and medium enterprises benefit from an all-in-one migration strategy. By transitioning all emails and data at once, your team can seamlessly log into Google Workspace on Monday morning and get straight to business.

Step 4: Prepare users for the switch from IMAP to Gmail

Moving away from a familiar email client or webmail interface can feel like a big change for staff, even if the underlying technology is outdated. Good communication and training help the migration succeed.

Focus on:

  1. Communication
    Explain why you’re moving from IMAP to Google Workspace, what will change (for example, using Gmail instead of the old webmail), and when.
  2. Simple user guides

    Provide short guides or videos showing how to log in, read and send email, manage labels instead of folders, and set up signatures.
  3. Support channels
    Make sure users know who to contact if they can’t find old mail, have issues with filters or struggle with the new interface.

A little preparation goes a long way to preventing “email panic” on cutover day.

Step 5: Carry out the IMAP to Google Workspace migration

The technical migration from IMAP to Google Workspace can usually be broken into clear stages:

1. Prepare Google Workspace

  • Create user accounts and groups.
  • Configure basic security, password policies and two-step verification.
  • Set up organisational units and admin roles if needed.

2. Connect to your IMAP server

  • Configure migration tools to connect securely to your existing IMAP server.
  • Verify access and run test migrations for a small number of accounts.

3. Migrate email data

  • Migrate email messages from IMAP mailboxes into the corresponding Gmail accounts.
  • Check that folder structures (now labels) and important messages are present.

4. Switch mail routing

  • Update DNS records (MX, SPF, DKIM, DMARC) so new emails are delivered to Gmail.
  • Monitor logs and user feedback during and after cutover.

5. Decommission or repurpose the old IMAP server

  • Once you’re confident everything is working in Google Workspace, decommission the old server or reduce it to a fallback role if appropriate.

Done properly, users can continue sending and receiving email with minimal disruption, and historical messages remain accessible in their new Gmail accounts.

How Refractiv helps UK SMEs with IMAP to Google Workspace migration

Refractiv specialises in helping UK SMEs move from legacy email platforms, including on-premise or hosted IMAP servers, to Google Workspace in a controlled and predictable way.

For IT managers, that means:

  • A clear, guided assessment of your current IMAP environment, including mailboxes, aliases and storage.
  • Help design your new Google Workspace structure, so users and shared addresses are organised logically from day one.
  • Support with the technical migration steps, from connecting to your IMAP server to switching DNS and verifying that mail flows correctly.

Instead of spending days digging through documentation and troubleshooting migration scripts, you gain an experienced partner who has been through the process many times.

Fixed set-up fee and fixed migration project quote

Budget predictability is especially important for SMEs. To make IMAP to Google Workspace migration easier to approve and manage, Refractiv uses a fixed-cost model.
Once the scope is agreed – number of mailboxes, shared addresses, data volume and any special requirements – you receive a fixed price for the IMAP to Google Workspace migration project.

With this approach, you can:

  • Present clear, documented costs to leadership or finance without worrying about hidden extras.
  • Avoid scope creep and back-and-forth negotiations during the migration itself.
  • Focus on planning and user support, rather than tracking unpredictable invoices.

For resource-constrained IT teams, this level of clarity can make the difference between “nice idea” and “approved project”.

Bundle migration with Google Workspace licences and ongoing services

Refractiv is not just a migration specialist; we also provide Google Workspace licences and ongoing support services. For IMAP to Google Workspace migration, this gives you a convenient way to bundle:

  • Google Workspace subscriptions matched to your size and needs.
  • Migration services for your IMAP email environment.
  • Ongoing services, such as training, security audits, admin panel reporting and UK helpdesk access.

Instead of buying licences from one supplier and trying to find another for migration, you deal with a single partner that understands your environment end-to-end.

This model is particularly useful for SMEs that want:

  • A trusted UK-based contact for all things Google Workspace.
  • Consistent configuration, licensing and support from day one.
  • A clear path for future improvements, such as adding shared drives, fine-tuning security or rolling out more collaboration tools.

Beyond the migration: training, security checks and UK helpdesk

Once your email is live on Google Workspace, you want users to feel confident and your environment to stay secure and well-managed. Refractiv can support you with:

  • Training to help staff get comfortable with Gmail, Calendar, Drive and other core apps.
  • Security audits and checks to ensure your Google Workspace configuration follows best practice, protecting both data and accounts.
  • Admin panel reports so you can see how the platform is being used, spot potential issues and plan improvements.
  • Ongoing access to a UK helpdesk for Google Workspace queries, giving your IT team a reliable escalation path.

Taken together, these services turn your IMAP to Google Workspace migration into the start of a more modern, secure and collaborative way of working.
