This array has come with the latest controller firmware (08.40.10.01), NVSRAM firmware&nbsp; (N5600-840834-D03) and ESM firmware&nbsp;(039F).<BR /><BR />However on cross-checking with IMT in order to run with the existing infrastructure we are looking at the latest compatible SANtricity OS version being 8.25.X (preferable) or 8.30.<BR />I have been searching with no luck in E-Series manuals for a supported downgrade procedure.<BR /><BR />If anyone is aware of this process or has a link to the same appreciate if it could shared here.<BR /><BR />Thanks in advance.</P> <P>&nbsp;</P> <P>Regards,</P> <P>CB</P> Wed, 04 Jun 2025 13:53:06 GMT https://community.netapp.com/t5/EF-E-Series-SANtricity-and-Related-Plug-ins/E5660-SANtricity-OS-Downgrade/m-p/139110#M537 netBC2015 2025-06-04T13:53:06Z https://community.netapp.com/t5/EF-E-Series-SANtricity-and-Related-Plug-ins/E5660-SANtricity-OS-Downgrade/m-p/139118#M538 <P>Hi,</P> <P>&nbsp;</P> <P>Please refer KB&nbsp;<A href="https://kb.netapp.com/app/answers/answer_view/a_id/1031585" target="_blank">https://kb.netapp.com/app/answers/answer_view/a_id/1031585</A> (requires login)</P> Mon, 26 Mar 2018 04:48:37 GMT https://community.netapp.com/t5/EF-E-Series-SANtricity-and-Related-Plug-ins/E5660-SANtricity-OS-Downgrade/m-p/139118#M538 Sahana 2018-03-26T04:48:37Z
