When upgrading WinCollect 7 standalone agents, the process differs slightly from that of managed agents. Unlike managed agents, standalone agents don't require an SFS file upgrade. Instead, you upgrade a standalone agent by installing the new executable file (.exe) directly on the host machine.
It's also essential to verify that the version of the WinCollect standalone agent installed on your hosts is compatible with the QRadar version you're upgrading to. If there's a mismatch, you may experience issues such as incompatibility, reduced functionality, or even failure to collect logs.
