Upgrading SAS Viya 2024.09 LTS to SAS Viya2025.03 LTS

[thesasuser]

Hello
We are trying to upgrade   SAS Viya 2024.09 LTS to SAS Viya2025.03 LTS and running into an issue.
In the 2024.09 LTS version the rabbitmq stateful sets confirm to the "sas" storage class whereas in the 2025.03 LTS version this storage class needs to be "io2-vol-mq".
The deployment appears to fail on this count.
Wondering if any body can enlighten us in making this change while retaining the old data?

This documentation discusses how to change the storage class for RabbitMQ, which is basically done by scaling down the service and removing the existing PVCs and adding/modifying a transformer to set a different storage class. The documentation notes this is a destructive event, so your caveat of "while retaining the old data" isn't followed here.

"IMPORTANT:
Re-creating the PersistentVolume is a destructive event. The allocated PersistentVolume must be deleted. All exchanges, queues, bindings, and any unread messages will be destroyed.
Performing the following steps causes an outage while RabbitMQ pods are stopped and restarted. Make sure that you plan for an outage before executing the steps. Note that the following instructions are only for RabbitMQ pods."
