@huseyinbabal Please also update this document https://docs.botkube.io/cli/migrating-installation-to-botkube-cloud

also as agreed on Slack, please describe that the extraObjects are not migrated. So the helm upgrade that we perform simply removes all of them, so if user had cluster roles or bindings there, then they need to migrate them on their own to make sure that migrated plugin RBAC config will work properly.
