If we migrate a SharePoint Server 2010 with Enterprise Client Access License to a SharePoint Server 2013 with Standard Client Access License, would we have issues? I presume we will have issues as this seems an upgrade in version but a downgrade in edition. I would like to hear your thoughts and experience.
Please refer to below earlier thread having suggested solutions might helps you to get in more detailed:
