Before you can upgrade your CRM 4 to 2011, you will need to uninstall all 3rd party addons and check that all buttons have been deleted. After the migration you can then install the latest version of each addon. Should you have not done this, then it will be more complicated to get rid of the buttons and icons before you can install the CRM 2011 addons.
Until now we have no installation routine for our Dashboards for MS CRM 2011. This is why this blog entry describes how to upgrade/install the Dashboards in a MS CRM 2011 environment manually.
Please note: This installation will only work in an on-premise installation and will not work in IFD and Claims-Based-Authentication-Mode.
If you upgrade from DocumentsCorePack (DCP) Server for MS CRM 2011 v5.5 to a higher version, you have to completely remove DocumentsCorePack Server for MS CRM 2011 from your CRM.
