If possible can you please provide the steps for me or point e the document as i not that much familiar with docker.

Please see https://develop.sentry.dev/self-hosted/#upgrading

It should be safe to upgrade from 9.1.2 to 20.8.0. I’d wait until September 15th, if you are not in a rush, for 20.9.0 to be out with a fix for upgrades from 9.1.2.
