SQL Safe 9.5 continues to use the WCF communication protocols introduced in 9.3. It is important to understand the impact on compatibility with older agent versions. This guide provides essential information to help you upgrade effectively.
- Incompatibility with older agents:
Agents older than 9.3 (including 9.2.2 and lower) that do not include the new protocols are not supported in a mixed-version environment with SQL Safe 9.5. - Backup processing:
Previously, you could upgrade the Management Service while still using older agent versions. However, upgrading the Management Service to 9.5 will prevent communication with agents older than 9.3 (including 9.2.2 and lower), as they do not support the new protocols.
These older agents will still process backups, but their statuses will not be reported to the Management Console.
Agents 9.3, 9.4, and 9.5 remain fully compatible with each other. - Upgrade wizard:
SQL Safe 9.5 provides a mass upgrade wizard to simplify the upgrade process for agents.
If you choose not to upgrade all agents, we recommend creating a new application server for SQL Safe 9.5. This setup allows you to split your assets between version 9.5 and older agents.
By following this guide, you can ensure a successful transition to SQL Safe 9.5 version while minimizing potential disruptions.
