how to perform cluster mode ontap upgrade from 8.2.3P2 to 9.0

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

Hello, Please consult a partner or professional service for the upgrade, because there was a network configuration change between both versions and the IMT (SW dependencies) have to be checked before. It's not possible to describe the complete upgrade steps here, because if something is missing then you need someone as soon as possible to reduce a possible downtime. The Upgrade Advisor in MyASUP can assist you during the upgrade procedure. Best regards, Marc

True.

ONTAP9 is still RC, not good for production systems. If I was the storage admin, I would wait for a GA release.

"What's in the name"? Today's RC was known as GA and today's GA was known as GD in the past. So the difference is mostly in amount of testing and length of exposure to "real world" workloads.

 

Quoting current release model definition:


RCs are fully tested and are suitable in development / test environments and in production environments, including those with business-critical workloads.


I do not endorse using RC, but at least we need to stay with facts Smiley Happy
