Preinstallation Checklist

---

Before proceeding with an Orchestrator upgrade/installation, carefully review the following task list:

Directly Updating Orchestrator

---

Installation artifacts are provided when you first purchase Orchestrator or they can be provided by your customer success manager or our support team. There are a few ways to directly update:

Using the Windows Installer

UiPathOrchestrator.msi performs an in-place update that copies all your settings and creates a backup folder for the old version. It is suitable for both one node and multi-node architecture. Some web.config settings are not copied if the version you are upgrading from was installed using the deprecated scripts. The repair functionality of the Windows Installer is not supported.
Learn how to update using the Windows installer.

Using the Azure Script

A complex update of Orchestrator and its components on one or multiple nodes, in the Azure Portal.
Learn how to update using the Azure script.

Using the UiPathPlatform Installer

An executable that enables you to update Orchestrator, Robot, and Studio. It is suitable for one-node architectures. The processes are the same as those you would go through using the Windows installers, UiPathStudio.msi and UiPathOrchestrator.msi.
Unlike UiPathStudio.msi and UiPathOrchestrator.msi, UiPathPlatformInstaller.exe does not accept command line arguments.

Update Considerations

---

Encryption

During an Orchestrator update, the installer cannot read an encrypted SecureAppSettings section within web.config . In order to read the EncryptionKey from Orchestrator's web.config and then migrate it into Identity Server's appsettings.Production.json, the key must be plain text. You need to manually decrypt the section before updating Orchestrator. After the Orchestrator update process was finalized, remember to re-encrypt the SecureAppSettings section in web.config.

Certificates

Note the new certificate requirements. If your existing certificate doesn't meet them, here is how to get a valid certificate and how to replace it in the existing Orchestrator instance, before upgrading.

For security reasons, for the certificate used to sign the access tokens generated by the Identity Server, make sure to use a public key on 2048 bits. The certificate's location has to be set within appsettings.Production.json's Signing Credential section.

Database

Regardless of how you choose to update, if the database you point to does not exist, it is automatically created while running the update. If you point to an existing database, it is updated during the same process. The Orchestrator SQL database is automatically set to be case-insensitive (“OrchDB” = “orchdb”) at installation.

External Providers

While performing the update, if you have any external providers enabled in web.config, you are prompted about the manual changes you need to perform on your preexistent external providers. Read here about the manual changes you need to perform.

Known Issues

Some antivirus software can prevent Data Migration scripts from functioning correctly during an upgrade.

After updating your Orchestrator from 2019.10 or older, the Profile page won't display login attempts previous to that update.

Package Migration

---

In v2020.10+, Legacy is no longer a supported NuGet repository type. Packages previously residing in a Legacy repository are migrated to a Composite repository. For composite repositories, package location is configured using the Storage.Type and Storage.Location parameters in UiPath.Orchestrator.dll.config. After the upgrade, all Legacy-related app settings become deprecated and no longer have an effect:

• NuGet.Packages.Path
• NuGet.Activities.Path
• Nuget.EnableRedisNodeCoordination
• Nuget.EnableNugetServerLogging
• NuGet.EnableFileSystemMonitoring
• NuGet.Repository.Type

The new package location depends on how you configured the NuGet.Packages.Path and NuGet.Activities.Path parameters in web.config for the previous Orchestrator version.

Default Location

If you stored the packages in the default locations (~/NuGetPackages and ~/NuGetPackages/Activities), the new package location becomes RootPath=.\Storage.

Custom Location

If you stored the packages in a custom location, during the installation you are asked for a new storage location. For silent installs, the STORAGE_TYPE and STORAGE_LOCATION parameters become mandatory, unless you specifically add them in web.config (Storage.Type and Storage.Location) prior to the upgrade.

Packages Migration Matrix

The matrix below describes when are the STORAGE_TYPE and STORAGE_LOCATION parameters requested or ignored during an upgrade. The matrix takes into consideration the version you are upgrading from, and package location customization in both the previous version and 2020.10.

Migration Errors

If, for any reason, package migration fails, you are presented with the following options:

• Retry - Package migration is restarted. Packages that have already been migrated are skipped.
• Abort - The installation is restarted. During the migration step, packages that have already been migrated are not skipped and are migrated again. For this reason, you may find duplicate files in different containers. This only happens when migrating from versions older than 2019.4.
• Continue - The migration is being carried on with.
