Obviously try it on a copy and/or subset of your data first (and keep a backup of the original for some time regardless)  also close down arcmap etc to get rid of any locks for renaming: import arcpy import os index_fc = r'C:\ArcGIS\yourFGDBgdb\Your index polygons' line_gdb = r'C:\ArcGIS\FGDB containing your lines.gdb' #list the fc names and paths to line FCs arcpy.env.workspace = line_gdb lines_fclist = [[fc, os.path.join(line_gdb, fc)] for fc in arcpy.ListFeatureClasses(feature_type="line")] #create a list to store FC name and #single line geom from each lines FC linefc_list=[] for line_fc in lines_fclist: with arcpy.da.SearchCursor(line_fc[1],["SHAPE@"]) as cursor: for row in cursor: linefc_list.append([line_fc[0],row[0]]) break #create a dictionary of line fc path and intersecting index polygon name index_line_dict = {} with arcpy.da.SearchCursor(index_fc,[“Tile_Num","SHAPE@"]) as cursor: for row in cursor: for line in linefc_list: if row[1].disjoint(line[1]) is False: index_line_dict[os.path.join(line_gdb, line[0])] = row[0] break print(index_line_dict) #rename lines to match for filepath in index_line_dict: arcpy.management.Rename(filepath,index_line_dict[filepath],"FeatureClass")     ...
