Can you please provide me the step by step procedure for upgrading from 5.4.2 to 6.7.2. My setup is running on containers and i dont want loose data as part of upgrade. How the database schema gets upgraded. documentation in the website is a bit unclear for containers solutions. Help me!!
While upgrading, I can see errors like “t=2020-05-04T06:24:18+0000 lvl=warn msg=“phantomJS is deprecated and will be removed in a future release. You should consider migrating from phantomJS to grafana-image-renderer plugin.
