How to Upgrade the Server

Server upgrades should be planned with backups, maintenance windows, version compatibility checks, and rollback preparation.

Common Symptoms

• Some modules are unavailable after an upgrade.
• Clients do not receive update prompts.
• The server address or client update address was not updated.

What to Check First

• Current server version and target version.
• Backup completeness and rollback plan.
• Client version compatibility.
• Whether services, ports, and certificates will change.

Recommended Actions

1. Back up data before upgrading.
2. Upgrade during a maintenance window.
3. Verify login, messages, files, Cloud Drive, and the admin console after upgrade.
4. Keep upgrade logs and rollback files.

When to Contact an Administrator or Operations Team

• The issue affects multiple users or the whole company.
• The fix requires restarting production services, replacing certificates, changing databases, changing file services, or updating License files.
• Provide the failure time, impact scope, screenshots, account information, client version, server address, and related logs when reporting the issue.
