Hi All,
we have 6 nodes cluster with OS version 8.2.3P2 cluster mode at our Prod and DR DC's, our remote site's has flexpod concept with 2 nodes of OS version 8.3. Currently we are planning to upgrade the OS version to 9.0
Please suggest and help how to upgrade from 8.2.3P2 to 9.0 and request to provide detail steps of the upgrade process with pre and post checks for this upgrade.
Also let us know do we have any compatibility issues or bugs on 9.0 version? We are using Hitachi storage array's in our cluster mode setup.
Regards,
Bhuvan
