Your backup is from a different version of Windows SharePoint Services and cannot be restored to a server running the current version. The backup file should be restored to a server with version '12.0.0.6535' or later.

I tried to backup and restore a site collection from our production server to development. Our production is MOSS 2007 64 bit and Development is MOSS 2007 32 bit.

I got the following error when tried to restore the backed up file

"Your backup is from a different version of Windows SharePoint Services and cannot be restored to a server running the current version. The backup file should be  restored to a server with version '12.0.0.6535' or later."

When I checked the version of each SharePoint site Site Actions > Site Settings, both had different versions. In order to have a successful restoration, we need to sync both the SharePoint versions.

We were having version 12.0.0.6535 in production and 12.0.0.6421 in development.

I have fixed the issue by installing KB983444 which brought the MOSS 2007 to version 12.0.0.6535.
Run the Config wizard after  patch/hotfix/kb applied.

I'm able to use stsadm to restore from my backup into the new MOSS 2007 site.

The file '/_Layouts/Bamboo.ProjectPortfolioDashboard/HandleDataForCharts.ashx' does not exist.

Issue: We have installed the Bamboo's Project Portfolio Dashboard solution in our production environment without any issues, however, when we add the Web Part, the images in the Web Part were not loaded and getting the following error

The file '/_Layouts/Bamboo.ProjectPortfolioDashboard/HandleDataForCharts.ashx' does not exist. at System.Web.UI.Util.CheckVirtualFileExists(VirtualPath virtualPath) at System.Web.Compilation.BuildManager.GetVPathBuildResultInternal(VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.Compilation.BuildManager.GetVPathBuildResultWithNoAssert(HttpContext context, VirtualPath virtualPath, Boolean noBuild, Boolean allowCrossApp, Boolean allowBuildInPrecompile) at System.Web.UI.SimpleHandlerFactory.System.Web.IHttpHandlerFactory2.GetHandler(HttpContext context, String requestType, VirtualPath virtualPath, String physicalPath) at System.Web.HttpApplication.MapHttpHandler(HttpContext context, String requestType, VirtualPath path, String pathTranslated, Boolean useAppConfig) at System.Web.HttpApplication.MapHandlerExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously) 

Note: Our SharePoint site is SSL enabled. The WebPart is working in http and not on Https. When contacted Bamboo we have been told that the issue is not with their setup and it is with our environment.

Resolution: We checked that the file HandleDataForCharts.ashx does exist at the _layouts folder. We finally found out that an HttpHandler entry is missing in the web.config file

We were able to  resolved the issue by adding the following web.config entry under <httpHandlers> section

<add verb="*" path="*.ashx" type="Bamboo.HandleDataHelper.HandleDataForCharts" validate="false" />
