We have run below on OBR server to restore the certificates:
ovcert -exporttrusted -file <filename> -ovrg server
ovcert -exportcert -file <filename> -ovrg server
ovcert -importtrusted -file <filename>
ovcert -importcert -file <filename>
!NOTE: In the instance, <filename> is the name with which you want to save the certificate.
Then, the output of “ovcert -list” was restored.
