Three ways to replace unsupported Exchange

MIGRATION QUESTIONS

What IT managers ask first

Yes. GFI Exinda AI is completely independent of your mail server. It continues optimizing VoIP, ERP, POS, and all application traffic throughout and after the migration. Nothing changes.
GFI Exinda AI customers migrating from Exchange 2016/2019 to GFI KerioConnect® receive a 30% discount plus Eloquens® AI free for year 1. Applied automatically. Your quote will reflect this.
No. KEMT performs a complete server-to-server migration. Every email, folder, calendar entry, and contact is preserved.
Yes. GFI KerioConnect® supports Outlook. Many organizations migrate using a phased rollout with no workflow changes for users.
Eloquens® AI responds to common emails automatically, in under 5 minutes, 24/7, in any language. It runs on GFI's secure cloud infrastructure and is included free for year 1 with this offer.
No security patches are released after end of support. Auditors flag unsupported software. For regulated sectors such as banking, insurance, and healthcare, this is an active compliance risk. GFI Exinda AI does not change this — it optimizes your network but does not patch your mail server.
Everything migrates. Nothing is lost. Users see all historical email in Outlook exactly where it was.

✅

Guide on its way.

A GFI partner will be in touch within 1 business day.

An on-premise mail server that handles email, calendar, contacts, and mobile sync. Installs on your own Windows or Linux hardware and replaces Exchange directly.

GFI KerioConnect® runs on your own server. Mail never leaves your infrastructure. M365 moves everything to Microsoft's cloud.

Small teams under 50 users: around 30 days. Mid-size (50–500): 60–90 days. Larger orgs: up to 5–7 months. Your free assessment gives a tailored estimate.

No, but every day on unsupported Exchange is a day without security patches. The sooner you begin, the sooner the exposure is closed.

Yes. Deploy GFI KerioConnect® in your own environment and run it fully for 30 days before any purchase decision.

Pre-migration assessment, KEMT access, step-by-step documentation, and GFI engineering support throughout. Your local partner is also available at every stage.

MIGRATION PLAN

A practical 30-day path off unsupported Exchange.

THE RISK OF STAYING

Every vulnerability since end of support is permanent.

Exchange 2016 and 2019 no longer receive security updates. GFI Exinda AI remains unaffected, but it cannot patch an unsupported mail server.

Migration changes Exchange only. 
Bandwidth management, application acceleration and network reporting continue uninterrupted.

Your network team does not lose visibility, QoS policies or traffic optimization because Exchange reached end of support. GFI Exinda AI continues optimizing VoIP, ERP and application traffic while GFI KerioConnect® replaces the exposed mail server on infrastructure you control.

Small teams are live in around 30 days without disrupting GFI Exinda AI optimization.
