I have made a backup of a SharePoint Site using Export-SPWeb. I have also added a new Host Named Site Collection and I would like to Import the Site into this newly created Host Named Site Collection.

I have managed to import it into a SubSite of another Site Collection but when I try with the Host Named Site Collection it gives the following error:

Import-SPWeb : Cannot find an SPWeb object with Id or Url : http://demo.[companyname].com. At line:1 char:1 + Import-SPWeb http://demo.[companyname].com -Path C:\Import\Backup\SiteBackup\20160524\F ... + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~ + CategoryInfo : InvalidData: (Microsoft.Share...CmdletImportWeb: SPCmdletImportWeb) [Import-SPWeb], SPCmdletPipeBindException + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletImportWe

  • Have you created a site at the location of your host named site collection? If not, create one first then import your web to overwrite it.

  • Yup, there is a site there as well. I also tried using a site collection backup but then it says Version String Too Long Or Too Short May 27, 2016 at 8:25
  • What account are you running PowerShell as? Make sure the account that's being used has DBOwner permissions to the content database. Try a Get-SPWeb.

Managed to get it right somehow. Seems when I was trying to restore it using a SiteCollectionBackup it gave an error:

Restore-SPSite: Version String portion was too long or too short.

When it gave that error it also deleted the Host Named Site Collection. So after when i tried to restore again using Import-SPWeb it couldn't find the URL for the HNSC because it has been deleted automatically.
