Hi foggy, thanks for your reply.
So am I correct saying that minor updates are supported without an official statement from Veeam and then later tested, verified and included in the next update? Because when asking Veeam Support they explicitly advised against updating to ONTAP 9.1 because 9.5 U1 only has been tested up to ONTAP 9.0.
My customer wants to go from ONTAP 8.3.2 to 9.1 as soon as possible but because only up to ONTAP 9.0 is currently supported by B&R, we've had to put this on hold. Furthermore when he asked when he can expect Veeam to support the new release, my answer being "I have no idea" was understandably not so well received.
Now I know by now that ONTAP 9.1 will be supported by B&R 9.5 U2 which is to be expected in May. It's just the fact of not knowing / not having a vague ETA that does not sit so well with my customers. They expect me and Veeam to tell them roughly when new Veeam updates are coming out to support new software releases of their chosen Global Alliance Partner, so they can properly do patch and update management.
