Migrate web sites from IIS6 to IIS8
Posted on 2014-09-10
I am attempting to migrate several websites from a Win 2003 X86 system running IIS6 to Win 2012 R2 X64 system running IIS8. At this point in time I am only concerned with running ALL websites in classic ASP mode. I believe I have all of the correct roles/features installed in order to support classic mode.
I have migrated six sites over to the new 2012 server and I have only one working so far. Switching between Classic 2.0 and 4.0 modes produces several different errors on various sites.
-Error 403 Access forbidden
-Could not load file or assembly 'App_Browsers' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.
I have experimented with "WebDeploy" using a ZIP package, but it doesn't appear to resolve any of the various errors I am receiving (Noted above). I also tried a tool called "IMET" from the MS IIS.net website and creates the website/AppPools etc, but still produces the same set of errors (Noted above)
Has anyone had success with migrating websites between IIS6 and IIS8 (Classic mode)? Any tips are truly appreciated.
