I have a feeling that I'm not framing this question properly and for that I apologize, nevertheless: My ArcGIS licensed products are on computer A.  My map data [.mxd, rasters, layers, etc.], including geodatabase, are on Computer B.  I do this I as I have offisite backup attached to Computer B.  Computer A has only local backup. Computer B is threatening to go south so I bought a replacement for it; called Computer C. I copied the database and map files from Computer B to Computer C, using the same directory names on both. i copied the .prj and .txt files and related subdirectories [which are in a subdirectory \ArcGIS on Computer B] to Computer C, keeping the same subdirectory name. I reset the Home directory in the Catalog so that it points to Computer C.  When I restart ArcGIS, I see the new Home directory. When I go to load a map [.mxd], however, I'm seeing the base map in it's proper extent, but I'm not seeing the layers that are associated with the .mxd file.  If I, however, authenticate to Computer B [the old one], all is well.  Obviously I've missed some step in the transfer, but I can't work out what that might be. Would very much appreciate a pointer to the appropriate part of the ArcGIS help file that explains this.  [I've tried various search options on the Help file, but never seem to get quite the right set of search words]. Many thanks,  Bill Cole ... View more

Have a feature class for gravel roads.  There are a lot of gravel roads on the map, but some of them need to be changed to paved roads for which there is a separate feature class.  How do I do this for the small number of already mapped gravel roads whose designation [feature class] needs to be changed without having to redraw the road?  I'm sure this must be a commonly used function, but I can't think of the correct set of words to use for searching the ESRI ArcGIS help file and Ive tried a lot. Thanks very much for any guidance offered. Bill Cole ... View more

Probably not a good idea, but I'm teaching myself ArcGIS. Have created a map using the ESRI topographic base map with old USGS topographic maps tiled on top and georeferenced.  The map has routes [polylines with M enabled] and points. I think that somehow I've managed to create this map without having to have a dataframe.  Here is an image of the Table of Contents. I need to create some Group Layers and I can't do that because there is no Data Frame.  Is it possible to recover from this error without having to recreate the whole map? Sheepishly ....
