<div dir="ltr"><div class="gmail_default" style="font-family:tahoma,sans-serif">In a previous design project, what was learned from the CER product team was that the CM version used by a CER Server Group is specific to that CER Server Group only. It is allowed to have one single CER cluster comprised of multiple CER Server Groups, where each group could be integrated with a different CM version. Note that I was not involved in the project past the design phase, so I am not sure how that turned out.<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Oct 21, 2015 at 1:50 PM, Heim, Dennis <span dir="ltr"><<a href="mailto:Dennis.Heim@wwt.com" target="_blank">Dennis.Heim@wwt.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
