                                    We would like to (finally!) upgrade a complete and working  DevExpress ASP.NET Web Form application from build 13.1.8  to the latest available DevExpress Build. (v18..2.x) . I know that there are many things to consider but I think this is the time to do it. We will like to plan and execute this carefully.

                                    Could you please provide us with a detailed road map for this including tips and tricks to be able to succeed with the minimum issues possible?

                                    We are missing so many new and fantastic features that we want to implement and also, to be current with the latest bells and whistles for the other platforms and products.

                                    Thank you in advance for your help!.

                                Hi John,

                                The steps to upgrade an old version to a new one are described in the Upgrade Notes article. Take a note to the "Upgrading ASP.NET Applications" section. Also, we have made breaking changes since v13.1.8 to v18.2.5 and provided the whole list of these changes:
                                form v13.1.8 to v17.2.11
                                from v18.1.3 to v18.2.5
                                Unfortunately, not all problems can be resolved automatically with Project Converter. The biggest breaking change was made in v14.2.3: BC2626 - Some classes related to DevExpress ASP.NET controls have been moved to the DevExpress.Web namespace. Although the Project Converter solves this breaking change automatically, in some cases, it may be necessary to manually fix this change.

                                In general, we recommend upgrading your project on a regular base. It guarantees that the process will be smoother. Let me know if you need further assistance.

                                  Hi Marina.

                                  Thank you for your answer.

                                  I do  understand the implications and your answer was right to the point.

                                  One last question,  though, if you don't mind:

                                  There is a warning under "Upgrading ASP.Net applications" notes that says:

                                  *Important*When deploying a website, remove old DevExpress assemblies from the server.

                                  When the application is Published, (IIS on my case) besides the directories Bin and Obj, where else there are more DevExpress assemblies needed to be taken care of? In which locations? Aren't those overwritten as they are Published?

                                  Please advise.

                                  Thanks again for all your Help!.

                                  If you don't install our installation to your server, it's enough to remove our assemblies from the Bin and Obj folders.

                                  Thanks for such a quick answer, Vova.
