Error migrating content from 3.7SP4 to 4.0RC
Hi,
I'm trying out the Sitefinity Migration Tool from CodePlex.
My Sitefinity 3.7SP4 .NET 3.5 site is multi-lingual (two languages).
I get the following error when running the migration of Pages:
Importing Pages...Error retrieving Pages:Unable to cast object of type 'Telerik.Cms.Data.CmsUrl' to type 'System.String'. at Telerik.Sitefinity.Services.Migration.MigrationExportService.GetPagesWithParent(Guid parentId, CmsManager cmsManager, List`1 pageList) in C:\Website37SP4\MigrationExportService\MigrationExportService.cs:line 944 at Telerik.Sitefinity.Services.Migration.MigrationExportService.GetPagesWithParent(Guid parentId, CmsManager cmsManager, List`1 pageList) in C:\Website37SP4\MigrationExportService\MigrationExportService.cs:line 973 at Telerik.Sitefinity.Services.Migration.MigrationExportService.GetPagesWithParent(Guid parentId, CmsManager cmsManager, List`1 pageList) in C:\Website37SP4\MigrationExportService\MigrationExportService.cs:line 973 at Telerik.Sitefinity.Services.Migration.MigrationExportService.GetPages() in C:\Website37SP4\MigrationExportService\MigrationExportService.cs:line 988 at SyncInvokeGetPages(Object , Object[] , Object[] ) at System.ServiceModel.Dispatcher.SyncMethodInvoker.Invoke(Object instance, Object[] inputs, Object[]& outputs) at System.ServiceModel.Dispatcher.DispatchOperationRuntime.InvokeBegin(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage5(MessageRpc& rpc) at System.ServiceModel.Dispatcher.ImmutableDispatchRuntime.ProcessMessage4(MessageRpc& rpc) at System.ServiceModel.Dispatcher.MessageRpc.Process(Boolean isOperationContextSet)Hello Michael,
Do you have several providers for CmsManager ? Inside MigrationExportService.cs the CmsManager class is create with a parameter - the provider which was also introduced in Sitefinity 3.7 SP3.
Best wishes,

Hi Ivan,
I have only one provider for CmsManager.
I modified some code, from line 944 in MigrationExportService.cs.
foreach (CmsUrl url in page.Urls)
mp.Urls.Add(url.Url);
Well I'm not 100% sure the code above is correct; I'm not getting the original error anymore, but I am getting a new one.
In MigrationControls.cs, line 71. ArgumentNullException.
File.WriteAllBytes(imageFileName, migrationControl.ImageData);
migrationControl.ImageData is null
Maybe it is corrupt data. There is no catch block for that exception.
Thanks,
Michael
Hello Michael,
Could you try the suggestions provided by me in this post. It looks like there is some issue with the tool. Also I assume that you have not touch the code so far, because i have upgraded 5 websites locally and none of them caused this issue. It is something specific to the page url or page structure you have.
Sincerely yours,

Hi Ivan,
I reverted my code changes, then applied the ones in your post.
I commented the following lines:
//ExternalUrl = page.ExternalUrl,
//if (page.DefaultUrl != null)
//
// mp.DefaultUrl = page.DefaultUrl.Url;
// if (!String.IsNullOrEmpty(page.DefaultUrl.QueryString))
// mp.DefaultUrl += "?" + page.DefaultUrl.QueryString;
//
//else
//
// mp.DefaultUrl = String.Empty;
//
I'm back to my original error:
Unable to cast object of type 'Telerik.Cms.Data.CmsUrl' to type 'System.String'.
Thanks,
Michael
Hi Michael,
I do not know what the problem could be. I will need a sample project ( web.config and database backup). You can provide me with an external link or FTP through our support system. If the files are up to 20 MB you can use our system uploaded.
