Transferring of the Master Page finished with the failure

Question

There are two SharePoint sites, each based on its own SharePoint installation. I have to copy the Master Page from one site to another.

I moved an items from Master Page Gallery, then I registered dlls are referred by ones. But dlls link to another elements what I can’t find on server. Eventually I have a broken page with message: “The type of control Eos.SharePoint.Common.Controls.BreadCrumbsControl is forbidden. This type isn’t found or not registered as safe” (Eos.SharePoint.Common – one of loaded and registered dlls). I’m not find the file “Eos.SharePoint.Common.Controls.BreadCrumbsControl” in the server file system (Where does it locate?).

SharePoint site, from where I try to transfer the Master Page, had been developed by other people. And I haven’t the list of a deployed assets to compose a Web Solution Package. I have not even found Visual Studio or SharePoint Designer on the server. So maybe I haven’t a necessary resources. Should I stop?

Do you have an experience with similar problems? Maybe an another ways exists e.g. displaying a set of Web Parts in the proper Master Page via frames (Page Viewer Web Part, Embed Code)?

Help me, Guys!!!)))

You can download an existing WSP file on your Farm using Powershell:

$frm = Get-SPFarm
$file = $frm.Solutions.Item("Eos.SharePoint.Common.wsp").SolutionFile
$file.SaveAs("c:\wsp\Eos.SharePoint.Common.wsp")

If you want to use it in any other web application, just go to Central Administration -> Solution Management -> click System Settings -> Manage Farm Solutions

Look for Eos.SharePoint.Common.wsp and activate it on your second web application as well.
