I am currently running Ontap 8.3.2 on our clusters. We have a Microsoft SQL cluster that runs off of a SAN SVM. We need to upgrade Ontap and are planning on going to 9.4. The SQL cluster nodes are running snapdrive 7.1.3, unified utils 7.0.5, snap manager 7.2.2.
My question is how do I procede? Do I need to upgrade the client stuff first (snap drive, manager, unified utils) or do I upgrade them after I do my ontap upgrade(s)? Also, from reading some of the docs, I need to upgrade snapdrive to 7.1.5 to support ontap 9 or higher. Can I install the newer snapdrive on top of the old version, or do I need to uninstall the old version first? Is a reboot required for the client installs?
Thanks for any help,
