Opening a COBOL 
                  		  or a PL/I 
                     		  project in 
                  		  Enterprise Developer modifies the 
                  		  .cobolProj 
                  		  and 
                     			 .pliProj 
                     		  files. Once modified the 
                  		  .cobolProj 
                  		  and 
                     			 .pliProj 
                     		  files 
                  		  are no longer backward compatible with older versions of 
                  		  Enterprise Developer. This prevents you from opening the same projects in earlier versions of 
                  		  Enterprise Developer. 
                  		  
                  Note: Micro Focus recommend that you backup your 
                     			 .cobolProj 
                     			 and 
                        				.pliProj 
                        			  
                     			 files before opening projects created in earlier versions of 
                     			 Enterprise Developer.
