Why Replacing Zoom Is Easy but Replacing Google Workspace Is Not

Some US SaaS tools can be swapped in an afternoon. Others are structural dependencies that take months to unwind. The difference comes down to four factors: identity embedding, data gravity, integration coupling, and format lock-in.

Migration Google Workspace Zoom Strategy

When European organisations start thinking about reducing their US cloud dependency, the first instinct is to rank their tools by risk and start replacing them. This instinct is correct. The mistake is assuming that every replacement is roughly the same amount of work.

It is not. Replacing Zoom takes an afternoon. Replacing Google Workspace takes months. The difference is not about the quality of alternatives. Good alternatives exist for both. The difference is structural: it comes down to how deeply the tool has embedded itself into the way your organisation operates.

Understanding this difference is the key to building a migration plan that does not stall at the first hard dependency.

Why Zoom Is Easy to Replace

Zoom does one thing: video calls. It does it well, but its relationship with your organisation is shallow.

No identity dependency. Zoom authenticates users, but it is not your identity provider. Nobody logs into Salesforce or Notion through Zoom. Removing Zoom does not break any other tool.

No data gravity. Zoom stores call recordings if you enable that feature. The recordings are downloadable as standard video files. There is no proprietary format, no metadata that is hard to export, no accumulated data that becomes harder to move over time.

No integration coupling. Zoom integrates with calendars to create meeting links. That is the extent of it for most organisations. The calendar integration is replaceable: any video conferencing tool can generate a meeting link that gets attached to a calendar event.

No format lock-in. Zoom uses standard video and audio protocols. Participants do not need a Zoom account to join most meetings. The protocol is not proprietary in any way that creates switching costs.

The replacement process:

  1. Choose an alternative: Jitsi Meet (open source, no account required), BigBlueButton (open source, good for larger meetings), Nextcloud Talk (integrated with Nextcloud), or a commercial EU option.
  2. Update your calendar template to include the new meeting link format.
  3. Tell your team. Done.

Total effort: 1 to 2 hours. Total cost: zero to minimal. Risk of disruption: near zero.

Why Google Workspace Is Hard to Replace

Google Workspace looks like a productivity suite. It functions as an operating system. The difference matters.

Factor 1: Identity Embedding

Google Workspace is your identity provider. When employees click “Sign in with Google” on any third-party application, they are creating a dependency on Google’s identity infrastructure. A typical 25-person organisation has 10 to 30 applications connected through Google SSO.

Replacing Google Workspace means replacing the identity layer that all those applications depend on. Each SSO connection must be remapped to a new identity provider (Keycloak, Authentik, or similar). Each connection is a separate configuration task with its own quirks: some apps support SAML, others only OIDC, others have custom OAuth implementations.

Zoom has zero identity dependencies. Google Workspace has dozens.

Factor 2: Data Gravity

Google Drive stores your files, but that is the simple part. The complex part is what happens to those files over years of use:

  • Permissions accumulate. Hundreds of sharing decisions, folder-level access grants, and inherited permissions build up into a structure that nobody fully understands and nobody documented. Recreating this in another system takes weeks of manual work.
  • Google-native documents are not files. A Google Doc is a database-backed object in Google’s proprietary format. When you export it, you get a .docx conversion. The original, with its comments, suggestion history, named versions, and real-time collaboration state, exists only inside Google.
  • Cross-references break. Documents that link to other Google Docs use docs.google.com URLs. Every one of those links breaks when you leave Google.

Zoom stores video recordings. They are standard files. You download them, you are done. Google Drive stores everything your company has ever created, in formats that are partially proprietary and wrapped in a permissions model that does not export.

Factor 3: Integration Coupling

Google Workspace connects to other tools in ways that Zoom does not:

  • Google Calendar is an integration hub. Calendly, SavvyCal, HubSpot, Salesforce, and other tools pull availability from Google Calendar and push events to it. Each connection must be remapped.
  • Gmail is a notification backbone. Automated emails from CRMs, ticketing systems, monitoring tools, and marketing platforms flow through Gmail. Send-as aliases, routing rules, and domain-level configurations all live in Google’s admin console.
  • Google Sheets is a database substitute. Many small organisations use Google Sheets as a lightweight database, with API connections to other tools. Apps Script functions extend Sheets in ways that break outside Google.
  • Google Chat/Spaces integrate with Drive. File previews, shared docs in chat, and collaborative workflows span both services.

Zoom connects to your calendar. Google Workspace connects to your calendar, your CRM, your marketing tools, your project management, your automation platform, and your internal communication.

Factor 4: Format Lock-in

Zoom uses standard video formats. Google uses proprietary formats for its core productivity tools.

Google Docs, Sheets, and Slides are stored in Google’s internal format. Export converts them, but conversion is lossy:

  • Complex formatting in Google Docs may not render correctly in .docx.
  • Google Sheets functions that use Apps Script custom functions break in Excel.
  • Charts and pivot tables sometimes lose formatting or data connections on export.
  • Slides with embedded Google Sheets charts lose the live data connection.

For a company with 50 Google Docs, this is a minor inconvenience. For a company with 5,000, it is a project in itself.

The Structural Spectrum

This difference between Zoom and Google Workspace is not binary. Every tool in your stack sits somewhere on a spectrum from “shallow integration” to “deep structural dependency.”

Easy to replace (shallow integration):

  • Video conferencing (Zoom, Google Meet)
  • DNS (Cloudflare, Route 53)
  • Scheduling tools (Calendly, Doodle)
  • Password managers (switching between 1Password, Bitwarden, etc.)
  • Static website hosting (Vercel, Netlify)

Medium difficulty (moderate integration):

  • Chat platforms (Slack, Teams): chat history is hard to migrate, but integrations are rebuildable
  • Project management (Jira, Asana, Linear): data is exportable, workflows need rebuilding
  • CRM (Salesforce, HubSpot): data is portable, but integration depth varies
  • Payment processing (Stripe, PayPal): code-level integrations require development time

Hard to replace (deep structural dependency):

  • Identity providers (Azure AD, Google as IdP): every other system depends on them
  • Productivity suites (Microsoft 365, Google Workspace): identity + data + format + integration combined
  • Cloud infrastructure (AWS, Azure, GCP): if you run custom applications on them

What This Means for Migration Planning

If you are building a migration plan, the structural spectrum tells you where to start and what to expect:

Start with shallow-integration tools. Replace Zoom, move DNS, swap your scheduling tool. These wins are fast, cheap, and build momentum. They also demonstrate to your team that migration is possible and that EU alternatives work.

Plan carefully for medium-integration tools. Allocate weeks for CRM and chat migrations. Map every integration before you begin. Accept that some history (chat logs, ticket archives) may not transfer perfectly.

Treat deep structural dependencies as projects, not tasks. Migrating away from Google Workspace or Microsoft 365 is a 3-to-9-month project depending on organisation size. It requires a dependency audit, a phased plan, parallel running of old and new systems, and dedicated project management.

Do not migrate your identity provider last. This is counterintuitive, because identity is the hardest dependency. But running a parallel identity provider early (even before migrating anything else) gives you a fallback if access to Google or Microsoft is disrupted. It also makes every subsequent migration easier, because new SSO connections go to the new provider by default.

The Real Lesson

The question “can we replace this tool?” is the wrong question. Every tool has alternatives. The right question is: “how deeply is this tool embedded in how our organisation works, and what does it take to remove it?”

For Zoom, the answer is: barely embedded, replace it this afternoon. For Google Workspace, the answer is: deeply embedded across identity, data, integrations, and document formats, plan accordingly.

The organisations that migrate successfully are the ones that understand this spectrum before they start, and build their plan around the hardest dependencies, not the easiest ones.
