I want to update our EXM version to the latest version. We are already on Update 1 but EXM 3.4 Update 2 solves a breaking bug for our client.
(importing HTML templates are broken after changes that were made to SPEAK in SXP 8.2 Update-3)
The download page specifies an update package and update instructions: https://dev.sitecore.net/Downloads/Email_Experience_Manager/Email_Experience_Manager_34/Email_Experience_Manager_34_Update2.aspx
First of all, the instructions mention the wrong prerequisite: Sitecore XP 8.2 (rev. 170713).
Which should be Sitecore XP 8.2 (rev. 170407) or Sitecore XP 8.2 (rev. 170614).
The instructions use the UpdateInstallationWizard and don't specify any kind of environment to use. So I'm assuming that I only need to install this update on the Content Management environment?
How can I validate that I don't need to install this update on the CD nor Processing servers?
