Hello, I currently have a DD160 on DD OS 5.4.1.1-411752 and I'm looking for a way to update it past 5.7 in order to continue using Veeam Backup & Recovery 10a which won't support DD OS 5.7 and lower. From what I've been reading, I need to go through updating to DD OS 5.6 first but sadly, DD OS 5.6.2.0-543944.rpm is no longer available for download and can't find it anywhere. Tried here but the .rpm is the only file unavailable: [URL] I understand that we're talking about an unsupported DD OS here but is there any other way of obtaining this intermediate version? I already have 5.7.5.20-604935 from which I hope to directly go to 6.1.2.70-654892 which I also managed to find.   Thank you!
Need Data Domain OS 5.6.2.0-543944.rpm
