Maintenance jobs

You can create the following maintenance tasks using Citrix Application Delivery and Management. You can then schedule the maintenance tasks at a specific date and time.

• Upgrade Citrix ADC instances

• Upgrade Citrix ADC SDX instances

• Upgrade Citrix ADC instances in the Autoscale Group

• Configure HA pair of Citrix ADC instances

• Convert HA pair of instances to Cluster

Schedule upgrading of Citrix ADC instances

1. In Citrix Application Delivery and Management, navigate to Infrastructure > Configuration > Configuration Jobs. Click the Create Job button.

2. In Create Maintenance Jobs, select Upgrade Citrix ADC (Standalone/High-Availability/Cluster) and click Proceed.

3. In Select Instance, type a name of your choice for Job Name.

4. Click Add Instances to add ADC instances that you want to upgrade.

   • To upgrade an HA pair, specify the IP address of a primary or secondary node. However, using the primary instance to upgrade the HA pair is recommended.

   • To upgrade a cluster, specify the cluster IP address.

5. Click Next to start the pre-upgrade validation on the selected instances.

   The Pre-upgrade validation tab displays the failed instances. Remove the failed instances and click Next.

   Important

   If you specify cluster IP address, the Citrix Application Delivery and Management does pre-upgrade validation only on the specified instance not on the other cluster nodes.

6. Optional, in Custom scripts, specify the scripts to run before and after an instance upgrade. Use one of the following ways to run the commands:

   • Import commands from file - Select the command input file from your local computer.
   • Type commands - Enter commands directly on the GUI.

   You can use custom scripts to check the changes before and after an instance upgrade. For example:

   • The instance version before and after the upgrade.
   • The status of interfaces, high-availability nodes, virtual servers, and services before and after upgrade.
   • The statistics of virtual servers and services.
   • The dynamic routes.

7. In Schedule Task, select one of the following options:

   • Upgrade now - The upgrade job runs immediately.

   • Schedule Later - Select this option to run this upgrade job later. Specify the Execution Date and Start Time when you want to upgrade the instances.

     If you want to upgrade an ADC HA pair in two stages, select Perform two stage upgrade for nodes in HA.

     Specify the Execution Date and Start Time when you want to upgrade another instance in the HA pair.

8. In Create Job, specify the following details:

   1. Select one of the following options from the Software Image list:

      • Local - Select the instance upgrade file from your local machine.

      • Appliance - Select the instance upgrade file from an Citrix Application Delivery and Management file browser. The Citrix Application Delivery and Management GUI displays the instance files that are present at /var/mps/mps_images.

   2. Specify when you want to upload the image to an instance:

      • Upload now - Select this option to upload the image immediately. However, the upgrade job runs at the scheduled time.

      • Upload at the time of execution - Select this option to upload the image at the time of upgrade job execution.

   • Clean software image from Citrix ADC on successful upgrade - Select this option to clear the uploaded image in the ADC instance after the instance upgrade.

   • Backup the ADC instances before starting the upgrade. - Creates a backup of the selected ADC instances.

   • Enable ISSU to avoid network outage on ADC HA pair - ISSU ensures the zero downtime upgrade on an ADC high-availability pair. This option provides a migration functionality that honors the existing connections during upgrade. So, you can upgrade an ADC HA pair without downtime. Specify the ISSU migration timeout in minutes.

   • Receive Execution Report through email - Sends the execution report in email. To add an email distribution list, see Create an email distribution list.

   • Receive Execution Report through slack - Sends the execution report in slack. To add a Slack profile, see Create a Slack profile.

9. Click Create Job.
