This change introduces following simplified steps to follow during config migration. ``` // Steps to move from version N to version N+1 // 1. Add new struct serverConfigVN+1 in config-versions.go // 2. Set configCurrentVersion to "N+1" // 3. Set serverConfigCurrent to serverConfigVN+1 // 4. Add new migration function (ex. func migrateVNToVN+1()) in config-migrate.go // 5. Call migrateVNToVN+1() from migrateConfig() in config-migrate.go // 6. Make changes in config-current_test.go for any test change ```
