An administrator will be given error "Operation failed, failed to install update: is a directory." while upgrading SRM / VR from 9.0.2.2 to 9.0.3
Once the ISO is attached to 9.0.2.2 and attempt running the install from the management UI (VAMI) above error is given
VMware Site Recovery Manager (VLSR) 9.0.2.2
VMware vSphere Replication Appliance 9.0.2.2
This is expected behaviour as there is no possibility to attach ISO to 9.0.2.2 and run standard upgrade to 9.0.3 version
9.0.3 Version | Build 24693627 has been simplified by combining multiple appliances for VMware Live SIte Recovery, vSAN Data Protection and vSPhere Replication into a single VMware Live Recovery Appliance
See below:
Deploy new VLR appliance and then Converge the appliance to 9.0.3
