Briefly, this error occurs when Elasticsearch has completed an upgrade process for all transforms, but no actions were required to be updated. This is not an error but an informational message indicating that the upgrade process has been completed successfully. If you were expecting some transforms to be updated, you might need to check if the correct transforms were targeted during the upgrade process. Alternatively, it could mean that all transforms were already up-to-date before the upgrade process was initiated.

Log Context
Log “Successfully upgraded all transforms; (updated: [{}]; no action [{}])” classname is TransportUpgradeTransformsAction.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :
final long noAction = updatesByStatus.getOrDefault(UpdateResult.Status.NONE; 0L);
final long needsUpdate = updatesByStatus.getOrDefault(UpdateResult.Status.NEEDS_UPDATE; 0L);
if (request.isDryRun() == false) {
transformConfigManager.deleteOldIndices(ActionListener.wrap(aBool -> {
logger.info("Successfully upgraded all transforms; (updated: [{}]; no action [{}])"; updated; noAction);
listener.onResponse(new UpgradeTransformsAction.Response(updated; noAction; needsUpdate));
}; listener::onFailure));
} else {
// else: dry run
