Hi all, what is the best way to keep previous roles and permissions intact while performing major upgrades on superset? Should we be doing "superset init" after upgrades? Is that mandatory? We end up losing any custom roles that we might have setup when we do "superset init". For instance, we are planning to upgrade from 0.36.0 version to 0.37.0. Do we need to run "superset init" as part of the upgrade process? Is the answer going to be the same for any future upgrade paths? Thanks...
