So, a macsec license would work on both Switch Engine and Fabric Engine no matter the order you started using either OS. You may have to reinstall the license, so far we've only installed and used the licenses on one OS.</P> Thu, 07 Mar 2024 13:54:59 GMT ØyvindN 2024-03-07T13:54:59Z https://community.extremenetworks.com/t5/extremeswitching-other/licencing-of-5420/m-p/99577#M4125 <P>Good evening,<BR />I hope my message finds you well.<BR />We have acquired Extreme Networks switches&nbsp; 5420&nbsp;series that came with ExtremeXOS and we want to migrate them to ExtemeVOSS.<BR />Our main concern is whether Extreme Networks licenses are linked to the serial number or the operating system, in other words, are ExtremeXOS licenses valid for ExtremeVOSS?</P><P>Thank you for helping us understand.</P><P>&nbsp;</P> Wed, 06 Mar 2024 16:34:55 GMT https://community.extremenetworks.com/t5/extremeswitching-other/licencing-of-5420/m-p/99577#M4125 kevariste 2024-03-06T16:34:55Z https://community.extremenetworks.com/t5/extremeswitching-other/licencing-of-5420/m-p/99595#M4126 <P>Licenses are linked to the hardware serial number.
