Hello, this is my very first post on my personal blog. Recently i have been working on a migration project, which we had to upgrade the existing infrastructure of RecoverPoints, the existing software version of the Recoverpoints were running on 3.x, to cluster it with the new Recoverpoint (5.x) i had to equivalent the software to same version. I was running on several issues during the upgrade. Since it was upgrading site by site, and the only option for deploying the .ISO image was via ftp, it was failing to fetch the existing image. Constantly i was receiving failures. The only solution to the existing problem was. Close the DM(Deployment Manager from EMC), and restart the session. Eventually after the restart it worked and it managed to upload the .ISO file to the appliance. Hope it might be helpful.
