4.2 Upgrade SEP Clients

Option A – Push upgrade via SEPM (recommended for scale)

• In SEPM console: Clients → select groups → Upgrade Clients → point to 14.3 client installer package.

Option B – Manual / scripted

• Deploy Setup.exe /s /v" REBOOT=ReallySuppress" via SCCM, PDQ, or login script.

Option C – GPO / WSUS (for unmanaged clients)

Phase 4: Post-Upgrade Validation

Common gotchas and fixes

• Database schema timeouts — increase DB timeout settings and ensure compatible DB version.
• Client check-in failures — verify firewall/port rules and proxy settings; restart the services.
• Performance spikes post-upgrade — check for scheduled full scans or background reindexing; throttle scan schedules.
• Mixed-version policy issues — ensure all management servers are fully upgraded before broad client deployment.
• Certificate trust errors — reissue or import certificates to trust stores on management servers and clients.

4. Clean Up

• Remove expired client packages and old logs.
• Run the internal DBVerify tool located in C:\Program Files\Symantec\Symantec Endpoint Protection Manager\bin\ to check for database corruption.

Option D: Third-party deployment (SCCM, PDQ)

• Extract SEP64.msi / SEP32.msi from the client ZIP.
• Deploy with REBOOT=ReallySuppress and transform (MST) for your settings.

2. Download SEP 14.3 Installer

• From Broadcom Support Portal (formerly Symantec FileConnect).
• Download the appropriate SEPM_14.3.x_Win64.exe (or Linux) and SEP_14.3.x_Client.zip.

Upgrade sequence (detailed)

1. Upgrade a test Management Server/console and validate UI and policies.
2. Upgrade database schema (if required) — follow vendor steps and ensure DB backups.
3. Update Secondary/Replication/Hot-standby servers next.
4. Update LiveUpdate/Update packages if separate.
5. Deploy client upgrade packages via management console to a pilot group (not broad push).
6. Monitor client check-ins and remediation events; only then expand to production waves.
