Between June and December 2026, Zendesk is forcing four separate migrations on its customer base. Not optional upgrades. Not recommended updates. Mandatory changes to mission-critical support infrastructure, each with a hard deadline and no option to opt out.
For support teams already stretched thin, the prospect of four forced migrations in six months — while simultaneously dealing with unpredictable outcome-based pricing — is pushing many to ask whether staying on Zendesk is worth the disruption.
Here's the full timeline, what each migration means for your team, and a practical plan for switching to something simpler before the deadlines hit.
The first wave of changes announced at Zendesk Relate 2026 starts rolling out. This includes:
Impact: Workflows built around the current AI setup may break or behave differently. Teams that relied on the old Essential AI tier pricing now face the optional $50/agent/month Copilot add-on plus per-resolution charges of $1.50 committed or $2.00 pay-as-you-go per automated resolution (zendesk.com/pricing, read 17 Oct 2026).
All legacy CC (carbon copy) accounts are auto-migrated to the new CCs and followers experience. This changes how email notifications work on tickets — who gets copied, how followers are managed, and how reply threading behaves.
Impact: This sounds minor until you realize how many teams built workflows around CC behavior. Automated ticket routing, escalation rules, and notification chains that depend on CC functionality all need testing and potentially rebuilding.
Zendesk stops all development on legacy AI agents. No new features, no bug fixes, no security patches.
Impact: Teams still running legacy AI after August 31 are on borrowed time. The system won't improve, bugs won't be fixed, and the gap between legacy and new capabilities will widen every week.
The final deadline. Legacy AI services are completely turned off. Every Zendesk customer must be on the new Forethought AI stack by this date.
Impact: This is the hard wall. If you're currently managing costs by staying on the older, cheaper AI tier, that option disappears on December 10. Migration to the new system — billed at $1.50–$2.00 per automated resolution, with Copilot an optional $50/agent/month add-on billed yearly — is mandatory.
Any one of these migrations would be manageable in isolation. But stacking four of them in a six-month window creates compounding disruption:
Every forced change needs to be tested against your existing workflows, automations, triggers, and integrations. Four migrations means four testing cycles — and with the first two hitting in June alone, teams have barely two weeks between them.
Your customers don't stop needing help because your helpdesk vendor is forcing infrastructure changes. Every hour spent on migration testing and troubleshooting is an hour not spent on actual support.
Migration #1 introduces outcome-based pricing. Migration #4 forces everyone onto it. Between June and December, teams face both the operational disruption of migrating AND the financial uncertainty of a new pricing model. Budget planning for H2 2026 becomes an exercise in guessing.
These aren't optional. Zendesk has made each migration mandatory with fixed deadlines. As one customer put it: "You don't force workflow-related changes onto mission-critical software without an option to disable it."
Beyond the migration disruption, the financial picture after all four migrations complete is stark. Based on confirmed pricing from Zendesk Relate 2026:
| Team Size | Zendesk Annual Cost | DeskLeap Annual Cost | Annual Savings |
|---|---|---|---|
| 5 agents | $115/agent/month in seats + $1.50–$2.00 per automated resolution | $0, or $1,740 with the AI Agent on all 5 | Depends on resolution volume |
| 10 agents | $13,800 in seats + $1.50–$2.00 per automated resolution | $0, or $3,480 with the AI Agent on all 10 | Depends on resolution volume |
| 15 agents | $115/agent/month in seats + $1.50–$2.00 per automated resolution | $0, or $5,220 with the AI Agent on all 15 | Depends on resolution volume |
| 25 agents | $115/agent/month in seats + $1.50–$2.00 per automated resolution | $0, or $8,700 with the AI Agent on all 25 | Depends on resolution volume |
Zendesk: Suite Pro ($115/agent) = $13,800/year for 10 agents, plus Copilot at $50/agent if you add it, plus $1.50 committed or $2.00 pay-as-you-go per automated resolution (zendesk.com/pricing, read 17 Oct 2026). DeskLeap: platform free; AI Agent $29/month each.
Teams across the industry are reporting 40–70% cost reductions by switching away from Zendesk. The cost difference alone funds the migration effort many times over.
If you're going to switch, doing it before June 12 means you skip all four migrations entirely. Here's the practical plan:
June 12 is the first deadline. After that, you're managing Zendesk's migration process AND evaluating alternatives simultaneously — the worst of both worlds.
Switching before the deadline means:
Switching after December 10 means:
The math and the timing both point the same direction: if you're going to leave Zendesk, doing it now saves the most money and the most disruption.
