Revert an update

Once the server has been updated, you can revert to the most recent version (one level back) using the revert-update tool. The revert-update tool accesses a log of file actions taken by the updater to put the file system back to its prior state. If you have run multiple updates, you can run the revert-update tool multiple times to revert to each prior update sequentially. You can only revert back one level. For example, if you have run the update twice since first installing the server, you can run the revert-update tool to revert to its previous state, then run the revert-update tool again to return to its original state.
