The mod file looks OK, while 5.2P1 Fixes some upgrade-related issues, this can be a browser refresh issue during the upgrade process. Did you raise a SR with support ? We need to look at the logs.  Regards, Idan
Hi, We are in the process of upgrading a eng test environment, but the upgrade is failing at 12% [IMAGE] [IMAGE]  Migration to ip communication is completed, system check, upgrade pre-req passes, -the change version requirements section, i've downloaded the a-cca.xml file manually.. i have two questions - - The Modification file, does this require changes from EMC support ? or is it just a check .. Currently it's not a registered system, does it have to be registered for the upgrade to complete ? - also can i tail a specific log file during the upgrade to find the issue... Cheer esxi & vc = 6.5
RP4VM 5.1.1.15 upgrade to 5.2
