Hi,

When checking the ISSU support matrix:

https://www.cisco.com/c/en/us/td/docs/switches/lan/catalyst_standalones/b-in-service-software-upgrade-issu.html#id_129556

and

https://www.cisco.com/c/en/us/support/docs/switches/catalyst-9500-series-switches/214406-in-service-software-upgrade-issu-on-ca.html#anc2

I only see the the cat3850 and cat900 switches from release 16.x an onward. Is ISSU supported on a Cat6807-XL VSS pair? More specifically from release 15.5.1SY2 to 15.5.2SY10.

Yes and no. 

ISSU is supported but ISSU does not support FPGA upgrade.

Please do not believe in the hype about ISSU, FSU/eFSU and use the normal commands.  ISSU, FSU/eFSU only work in "corner cases", labs and/or demos. 

The hassle of fixing a broken ISSU, FSU/eFSU upgrade can be a humiliating, humbling and lonely drive to the site.  The good part to all this (driving to site alone) is:  No one can hear you scream (or cry).
