Grafana Icons missig after upgrade

Hi Team,

Grafana Dashboards, Alerting, configuration and admins icons are missing after upgrading version from 6.4.4 to 7.0.6. ( Screen shot attached ). For upgrading, I replaced only “conf” folder in binaries.

OS: RHEL 7.8
Installation Method: Standalone Linux Binaries ( Open source standalone Linux binaries.)

Regards,
Sreehari

can you upgrade to the latest version?
