Upgrade EPiServer CMO with CMS 8

Prerequisites

It's recommended to upgrade the website to .NET Framework 4.5 and update NuGet packages to corresponding 7.5.x version:

• EPiServer.CMS.Core should be updated to 7.14 or later version.
• CMO should be updated to 7.5.446.2 or later version.

Upgrade CMO

1. Run the following command to move the protected modules and add-ons (including CMO and Live Monitor) to a location in the /modules/_protected directory:
   Move-EPiServerProtectedModules
2. Update Optimizely Content Management System (CMS 8) platform and CMO by running the Update-Package commands. Make sure that you run the Update-Package EPiServer.Cmo first for correct update order:
   Update-Package EPiServer.Cmo
Update-Package EPiServer.Cms
3. Update the CMS database to the latest version by running the following command:
   Update-EPiDatabase
4. Optional: Install the latest Live Monitor package. The EPiServer CMO does not have a direct dependency on Live Monitor. Live Monitor package for CMS 7.5 may be removed by NuGet when upgrading the CMO package to the latest version.
   Install-Package EPiServer.LiveMonitor
5. Optional: Configure Live Monitor and related components.
   Basically, you need to add assembly redirects for SignalR components and define EPiServerLiveMonitorOWINStartup as a startup value.
   This step is required only if you have the latest Live Monitor installed.
6. Rebuild the solution.
