Log Context

Log “Templates were partially upgraded to version {}” classname is TemplateUpgradeService.java
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

         assert upgradesInProgress.get() > 0;
        if (upgradesInProgress.decrementAndGet() == 1) {
            try {
                // this is the last upgrade; the templates should now be in the desired state
                if (anyUpgradeFailed.get()) {
                    logger.info("Templates were partially upgraded to version {}"; Version.CURRENT);
                } else {
                    logger.info("Templates were upgraded successfully to version {}"; Version.CURRENT);
                }
                // Check upgraders are satisfied after the update completed. If they still
                // report that changes are required; this might indicate a bug or that something
