Upgrade Wizard for Pronghorn (IAP)

The following steps need to be completed on each instance of IAP. If operating in a clustered environment, please ensure that all instances are updated. Since all instances of IAP attached to a mongoDB will pickup tasks to be worked in a job, having multiple versions of IAP operating on a single MongoDB instance may cause inconsistencies in task processing.

Verify Install Space Exists

  1. SSH into all the IAP servers as admin user. Alternatively, you can sudo to an admin user after logging in.

  2. Check diskspace. Remove older Pronghorn versions as needed.

    df -kh

    Make sure <PRONGHORN_HOME> is less than 70% full.

Run the Upgrade Wizard

  1. Run install commands on server. The bin file does not need to be in the <PRONGHORN_HOME> directory.
   cd <PRONGHORN HOME>
   ./itential-<build-id>.bin -h

Example Output

   USER@HOSTNAME pronghorn % ./itential-bundle-5-20193_2019.3.6.linux.x86_64.bin -h

  1. Run the following.

    bash ./itential-bundle-5-20193_2019.3.6.linux.x86_64.bin -e

  2. When prompted to extract, type 'y' then press enter.

  3. Copy over previous Pronghorn (IAP) configs.

   cd itential-bundle-5-20193_2019.3.6
   cp ./properties.json ./properties-orig.json
   cp ../current/properties.json ./properties.json
  1. Copy over previous Pronghorn (IAP) keys.
   cp -R ../current/custom ./
   cp ../current/keys/* keys/
  1. Copy over previous Pronghorn custom folders.

    cp -R ../current/node_modules/@itentialopensource ./node_modules

    This step might fail if the previous version of Pronghorn (IAP) was not using any Itential Open Source services.

  2. Copy over previous Pronghorn (IAP) custom applications. This step may take 3-8 minutes to complete.

    cp -R ../current/node_modules/@<custom app names> ./node_modules

Alert This step is required only if you did not run the Wizard Update.

  1. Change directory to the Pronghorn home directory.

    cd <PRONGHORN_HOME>

  2. Unlink current with rm command. The name of this file will depend on the exact build you were on.

    rm ./current

  3. Create the new link.

    ln -s <IAP 2020.1 Version> current

Migration Scripts

  1. Change directory to the migration script database, then run the scripts.
   cd <PRONGHORN_HOME>
   cd ./current/node_modules/@itential/pronghorn-core/migration_scripts
   node migratePropertiesToDatabase.js

Important Info

  • When prompted to enter (y/n) enter 'y'.

  • Running node migratePropertiesToDatabase.js unattended will automatically respond yes to all prompts, requiring no user input.

  • During an upgrade, a database backup will be triggered via installer script. For instances where IAP is connected via SSL to a Mongo database and Mongo is configured with the requireSSL property, the backup may fail with the following message:

      Failed: error connecting to db server: no reachable servers.
  1. Respond to the migration script prompts to match the deployment environment.

   **Note:** The migration script output above assumes that RabbitMQ is running on the same node as IAP, using default RabbitMQ credentials, and has SSL disabled. For security reasons this RabbitMQ configuration is not recommended for a production environment.

1. If you have already migrated, a notification will be displayed indicating this.

bash
Retrieving properties.json file…
Found properties.

Already Migrated!

1. The migration script will migrate much of the  `/opt/pronghorn/current/properties.json` content to the Mongo database.
1. A backup of the original `properties.json` file is generated during migration and will appear similar to the following.

bash
/opt/pronghorn/current/properties_4d37a26d-e5e1-4796-845d-220f09681d65.json

1. Note any adapter schema errors in startup logs. Errors for adapter schema issues should be fixed in the  `properties.json`  file, or using the  **System > Adapters**  view.

### Normalize Groups Scripts

The following procedure is only necessary if upgrading from 2019.3.2 or lower to release version 2019.3.3 or higher. If you have already performed these steps in an update to 2019.3.3 or above, then this procedure is not needed. There is no harm, however, in double-checking to be sure whether or not these steps may apply.

To run normalizeGroups script:

bash
cd /current/node_modules/@itential/app-workflow_engine/scripts
npm run index
npm run normalizeGroups

It is very important that you ensure all indexes are setup correctly on Jobs and Tasks. If you are missing any indexes, it may take 15-30 mins to complete the index creation on large databases.

The script will modify each job within the database, so depending on the number of jobs it may take 5 - 15 mins to complete. This is the slowest method because it is run from the IAP server and is only recommended for instances where the jobs collection is moderately sized (low 10K number of records).

### Migration Scripts

The following procedure is only necessary if upgrading from 2019.3.2 or lower to release version 2019.3.3 or higher. There is no harm in running these scripts again. Workflows can only be migrated once. If this script is needed to run on the workflow for a second time, the workflow will need to be re-imported into IAP and the script ran again.

To run migration scripts:

bash
cd /current/node_modules/@itential/app-workflow_engine/migration_scripts
node migrateWorkflows
node migrateJobsAndTasks20192

### Compatibility Check Scripts

Automations (within the Automation Studio) no longer allow tasks that export more than one job variable or that attach translations to exported job variables within automations. Workflow Engine will not support running automations with tasks that have translations on your outgoing data, or export more than one job variable as outgoing data. These steps will ensure this issue is resolved.

1. Run normalizeGroups script.

bash
cd /current/node_modules/@itential/app-workflow_engine/migration_scripts
node compatibilityCheck20193Maintenance.js

2. If any automations are discovered to be incompatible, please refer to the [Breaking Changes](http://docs.itential.io/2019.3/product/Breaking%20Changes/#modify-the-automation-to-fix-incompatibility) document to resolve them.

bash
$ cd /opt/pronghorn-core/node_modules/@itential/app-workflow_engine/migration_scripts/
$ node compatibilityCheck20193Maintenance.js

incompatibleWorkflow contains incompatible tasks:

getAdaptersForDevice (508a) Task Summary: exports more than one job variable Reason: Task exports more than one job variable, each of which may or may not have translations attached to it. locateDevices (e7c) Task Summary: exports a job variable with a translation Reason: Task exports a job variable with a translation attached to it.

locateDevices (37ec) Task Summary: exports more than one job variable with translations Reason: Task exports more than one job variable, each of which may or may not have translations attached to it.

RunCommand (2aed) Task Summary: exports more than one job var with no translations Reason: Task exports more than one job variable, each of which may or may not have translations attached to it.
```

Note: For ease of reference, the script output provides the name of the automation (e.g., incompatibleWorkflow), and the taskname (e.g., getAdaptersForDevice and locateDevices).
