Upgrading ServiceControl from version 2 to version 3 is a major upgrade and requires careful planning. During the upgrade process, the instance of ServiceControl that is being upgraded will no longer be available and will not be ingesting any messages.
Prerequisites
Before upgrading to ServiceControl version 3 the instance being upgraded must be upgraded to at least version 2.1.5.
For more information how to upgrade from Version 1.x to 2.1.5 consult the upgrade documentation.
Install .NET 4.6.1
The minimum .NET version for ServiceControl version 3 is .NET 4.6.1.
If not already installed, the ServiceControl installer will install .NET 4.6.1 silently during the installation process.
To determine which .NET Framework versions are installed, consult the Microsoft .NET Framework guidance.
Obsolete configuration sections
The following configuration sections are no longer supported and can be safely removed by deleting the section reference as well as the section itself.
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="AzureServiceBusQueueConfig" type="NServiceBus.Config.AzureServiceBusQueueConfig, NServiceBus.Azure.Transports.WindowsAzureServiceBus" />
</configSections>
<AzureServiceBusQueueConfig ... />
</configuration>
or
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<configSections>
<section name="AzureQueueConfig"
type="NServiceBus.Config.AzureQueueConfig, NServiceBus.Azure.Transports.WindowsAzureStorageQueues" />
</configSections>
<AzureQueueConfig ... />
</configuration>
The transports above have been tweaked with sensible defaults and manual configuration is no longer necessary.
Upgrading ServiceControl
Once the prerequisites are met the upgrade to ServiceControl version 3 can be done as an in-place upgrade.
Time for upgrade
This upgrade does not contain any data migrations, so the size of the database does not have any impact on the time to perform the upgrade.
