We used the upgrade advisor and everything went fine on one node. I didn't see anywhere in the documentation to not failover until the code has been updated on both filers before doing a failover. I am now in a state where my secondary node is in takeover mode and updated all the firmware on the shelves/etc. If I try and fail back to the primary it gives many errors and dumps the core and reboots.</P> <P>&nbsp;</P> <P>I'm not sure what to do at this point. I understand that I made a mistake at some point, but I would like to know next steps to see what I can do to recover this issue.</P> <P>&nbsp;</P> <P>Thanks,</P> <P>&nbsp;</P> <P>Matt</P> Wed, 04 Jun 2025 22:56:04 GMT https://community.netapp.com/t5/ONTAP-Discussions/Issues-after-upgrading-to-8-1-4/m-p/111972#M23708 MATT_PAULIKOT 2025-06-04T22:56:04Z https://community.netapp.com/t5/ONTAP-Discussions/Issues-after-upgrading-to-8-1-4/m-p/112036#M23726 <P>Likely you will need to call into support to get some help there.</P><P>&nbsp;</P><P>Otherwise, the node that is running - is it running 8.1.4 now or the older version?
