Before you begin

  1. Check the Activity Log in your OnApp CP dashboard if there are no transactions running in your cloud. If so, wait until all transactions are complete.
  2. Make sure no Control Panel files are open for editing under the root user account.

  3. If you are using a third-party billing platform, please ensure that this is compatible with OnApp 4.1 before proceeding with the upgrade! The latest WHMCS modules can be found here.

  4. If you are using WHMCS modules, make sure to update the PHP Wrapper after you update OnApp Cloud. Download the latest wrapper.

  5. We strongly recommend that you test all your custom scripts before upgrading your production environment.

  6. Be aware that OnApp does not support UEFI on static compute resources. You should disable UEFI on your compute resources before installing OnApp.
  7. Installer output is redirected to ./onapp-cp-install.log

  8. All installer critical errors are in /var/log/messages


    Drives assigned for use by Integrated Storage are identified using a disk signature that is generated using SCSI page query mechanism to the device. Please note that disk signatures may change across different kernel versions following an upgrade and reboot. If this occurs, go to the compute resource edit page to re-identify and select the correct drives. Please contact support if you have any concerns regarding this operation.

Getting support for your upgrade

You can use the information in this document to perform your own upgrade to the 4.1 version of the OnApp Cloud. However, if you have a full OnApp Cloud license, you are entitled to free upgrade support from the OnApp Support team.

If you would prefer to have the Support team perform the upgrade for you, just raise a ticket in the normal way. Please be aware, however, that there may be a queue!
