ISSU Criteria Summary
The following example shows a case when a few clients are connected to the FTP server,
and the FTP ISSU state becomes conditional. However, unified ISSU begins without any
error. All existing connections are dropped when you issue the issu start command and
the upgrade runs.
ISSU Criteria Summary
The following example shows when an ongoing file transfer operation is detected during
the initialization phase or validation phase. In this case, the prerequisite verification that
unified ISSU performs fails. Unified ISSU does not proceed until the active file transfer
operations are terminated. Issue the ftp-server flush command to forcibly terminate all
FTP sessions.
