Executive Summary — EPLAN Rehost 2026 Review

Future Outlook: ReHost Beyond 2026

EPLAN has indicated that by EPLAN 2028, traditional dongle‑based licensing will be phased out for new customers. ReHost 2026 lays the foundation for a fully cloud‑native license mobility system, where licenses follow the user identity (SSO) rather than a hardware hash. For now, ReHost 2026 is the essential bridge between legacy and modern licensing.

8. Security & Compliance Notes

• EPLAN 2026 introduces mandatory two-factor authentication (2FA) for any rehost initiated from a new geographic location (IP address change >500 km).
• Rehost events are recorded in the EPLAN Audit Trail for GxP environments (FDA 21 CFR Part 11 compliance).
• Unauthorized rehost attempts (e.g., using stolen credentials) trigger automatic license freeze and notify the contract owner via email and SMS.

Part 8: Future-Proofing Beyond 2026 – Will Rehosting Even Exist?

EPLAN is evolving toward a fully user-attached identity model, similar to Microsoft 365. By 2027 or 2028, the concept of “rehost” may disappear entirely. Instead: eplan rehost 2026

• You will simply sign in on any computer, and EPLAN will automatically deactivate the previous session (concurrent session limit applies).
• Hardware IDs become irrelevant – licensing moves to Just-in-Time (JIT) token issuance.

However, until then, EPLAN Rehost 2026 remains a critical process for every engineering organization that relies on continuity. Executive Summary — EPLAN Rehost 2026 Review Future

Issue 2: Firewall Blocking Port 8081

Error: "Connection to license broker timed out." Fix: The new EPLAN License Server 2026 uses WebSocket Secure (WSS) on port 8081 outbound. Your corporate firewall must allow traffic to *.eplan-license.com. Static IP whitelisting is recommended, not DNS filtering. where contract allows)

Why Rehosting Exists

• Hardware failure (motherboard, SSD, or network card change)
• Workstation upgrade (new PC for a designer)
• Virtualization (moving a license from a physical PC to a VM or cloud instance)
• User role change (transferring a floating license between departments)
• Server migration (moving the EPLAN License Manager to a new server OS)

Without a proper rehost, EPLAN will see the license as “still active” on the old machine, leading to error code EPL-14001 or License key already in use.

4.1 On the Source Machine (Old Host)

1. Open EPLAN License Manager → Tab: Licenses.
2. Right-click the active software container → Return License.
3. Select reason: Hardware change, OS reinstall, or User transfer.
4. System generates a return token (automatically sent to EPLAN cloud). No manual file handling required.

2. Cross‑Model Conversion Support

You can now rehost between:

• Dongle (hard key) → Software (Softlock)
• Named User → Network Floating
• On‑Premises → EPLAN Cloud (and vice versa, where contract allows)
