As SQL Safe 9.3 introduces new CWF protocols, 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:
With the introduction of CWF in SQL Safe 9.3, previous agent versions that do not include the CWF changes are no longer supported in a mixed version environment. - Backup processing:
Previously, you could upgrade the Management Service while still using older agent versions. However, upgrading the Management Service will prevent communication with those prior agent versions, as they do not use the new CWF protocols.
Although older agents will still process backups, their statuses will not be sent to the Management Console. - Upgrade wizard:
SQL Safe 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 9.3. This setup allows you to split your assets between version 9.3 and older agents.
By following this guide, you can ensure a successful transition to SQL Safe 9.3 version while minimizing potential disruptions.
