Hi. There are many changes between EPiServer CMS4 and CMS5. Take a look at the breaking change articles here: http://www.episerver.com/en/EPiServer_Knowledge_Center/Documentation/Release-Notes---EPiServer-CMS-51/Breaking-Changes/ For a couple a days ago we had a techforum for the developers in Norway. You can take a look at the presentations here: http://www.episerver.com/no/EPiServer/NyheterEvents/EPiServer_Events/Tidigere_Events/TechForum-13-november-2007/ One of the sessions was about converting a module from EPiCode from CMS4 -> CMS5. Also keep an eye on the RSS at https://www.coderesort.com/p/epicode/timeline. /Øyvind

Thanks, sooo.... EPiServer.Configuration replaces EPiServer.ApplicationConfiguration? Because that did not work. And I still can't find what is replacing EPiServer.SystemPage. SystemPage is dokumenteed in EPiServer 4.x SDK, but not in the 5.x SDK.

I have similar problems while migrating 4.61 project to 5.1.422.4 1. Which namespace contains episerver:PageSearch? Generation of designer file failed: Unknown server tag 'EPiServer:PageSearch'. I have found it using reflector in EPiServer.Legacy4 dll, but have failed to use it (using) even though it is within references. Is that control supported and if now what should I replace it with? 2. Then there is EPiServer.WebControls.FriendlyUrlRegistration which cannot be found. Is it moved somewhere like in Legacy4 or depricated? 3. Same thing goes for UserSid and SidCollection. Where are those classes or what is recommended to replace them? Thanx for any help

SystemPage in EPiServer 4.X is moved to EPiServer.UI.SystemPageBase in EPiServer.UI.dll! You will find EPiServer.UI.dll in your CMS bin folder.

1. Which namespace contains episerver:PageSearch? -> The PageSearch control has been replaced with SearchDataSource. Look on the implementation in the public template set to see how this can be used. The PageSearch still exists in the EPiServer.Legacy4 dll for backwards compability. 2. Then there is EPiServer.WebControls.FriendlyUrlRegistration which cannot be found. Is it moved somewhere like in Legacy4 or depricated? -> This control has been depricated and is not needed any more since friendly url has been totally rewritten. 3. Same thing goes for UserSid and SidCollection. Where are those classes or what is recommended to replace them? -> The user handling has been completely rewritten in EPiServer CMS 5. We are using the provider model in .NET 2.0 to handle authentication, members, groups and profiles.
