Dekho V 4.1.9 includes a new and improved upgrade tool to migrate your maps, queries and bookmarks automatically. This tool performs a side-by-side migration; Both the old Dekho 4.0.6 and the new V4.1.9 must be running at the same time. They can be installed on different servers. The upgrade tool extracts your old config MXD and injects new templates and maps into the new Dekho 4.1 system. The migration tool re-connects your queries, roles and bookmarks automatically. [..]

The upgrade tool is located inside the Dekho 4.1.9 release package, under \Utilities\Dekho407to419UpdateTool.
