Issue/Introduction

If SDDC Manager is upgraded from 5.x to 9.0.x, restoring from file-based backup fails, because the restore-configuration.sh scripts attempts to recover the feature.properties file from a relative path, rather than the absolute path.

The following error appears in /var/log/vmware/vcf/sddc-support/vcf-sos.log:

Environment

SDDC-Manager 9.0.x

Resolution

Workaround:

1. Power off the current SDDC-M appliance. Deploy a fresh SDDC Manager appliance using the OVA file and start the SDDC-M Restore process again.
2. Perform the usual pre-restore steps: Power on the newly deployed SDDC Manager appliance, copy the encrypted backup file to the /tmp folder, and generate an authentication token.
3. Before invoking the SDDC-M Restore API, SSH into the new SDDC-M appliance as the root user and run the following command (this updates restore-configuration.sh and creates a backup of the original file as restore-configuration.sh.bak):
   
   sed -i.bak -e 's|\[ ! -e "\$file" \]|[ ! -e "$base_directory$file" ]|' -e 's|\[ ! -d "\$dir" \]|[ ! -d "$base_directory$dir" ]|' /opt/vmware/sddc-support/scripts/restore-configuration.sh
   
   
4. Run the SDDC-M Restore API and proceed with the remaining steps as usual.
