[Rancher] Can Rancher Support validate our planned upgrade?

Rancher Support recommends Customers to notify them ahead of planned maintenance events for upgrade and migration. The notification can be made as a support case. At a minimum, this case should have information on:

• Current Rancher version
• Target Rancher version
• Reason for upgrade
• Upgrade date and maintenance time window

But it would be best if Customer could provide the requested information in a document (please ask for the "Upgrade Notification RFI Template" in the support case). Based on the information provided, Rancher Support can provide any applicable advisories to the Customer for the planned event. Rancher Support may request Customer to run specific information gathering scripts. Data collected from these scripts will be used by Rancher Support to understand the Customer deployment and validate the upgrade path that is being considered.

Note 1: On all regular, planned upgrades, Rancher Support requests Customer to notify as early as possible. Notifications that are one (1) calendar week in advance provide reasonable time for Rancher Support to follow up with any applicable advisories.
Note 2: A Supportability Review is suitable to be run in advance of such a planned activity if the customer can afford the time to run it. Please, consult the Rancher Supportability Review Guide for more information.
