So licensing a QlikView November 2018 or April 2019 release with a LEF / control number from 11.20 is fine.</P> <P>What's important though is that they have a&nbsp;<STRONG>valid maintenance agreement</STRONG>. If the maintenance has expired prior to the product being released, the license will not be accepted.</P> <P>See the <A href="https://help.qlik.com/en-US/qlikview/November2018/Subsystems/Server/Content/QV_Server/QlikView-Server/QVSRM_MaintenanceContract.htm" target="_blank" rel="noopener">QlikView Help</A> for details.&nbsp;</P> <P>You'd be looking for a line in the LEF like this:</P> <P>PRODUCTLEVEL;<STRONG>10</STRONG>;;2020-01-31</P> <P>The 10 means "QlikView Server".
