Cannot restore site backup - schema version does not match

Hi all,

Is it possible to restore a site backup from an earlier version of SharePoint 2013 onto a newer version of SharePoint 2013?

How?

I try to restore a site backup with the PowerShell command Restore-SPSite.

Although the error in PowerShell is not very helpful:

    + CategoryInfo          : InvalidData: (Microsoft.Share...dletRestoreSite:SPCmdletRestoreSite) [Restore-SPSite], DirectoryNotFoundException
    + FullyQualifiedErrorId : Microsoft.SharePoint.PowerShell.SPCmdletRestoreSite

I get the following error in my ULS log:

Could not deserialize site from <path>. Microsoft.SharePoint.SPException: Schema version of backup 15.0.4420.1017 does not match current schema version 15.0.4481.1005     at Microsoft.SharePoint.SPSite.Restore(String filename, Boolean isADMode, Boolean& readOnlyMode, Boolean& hadWriteLock)

Apparently this error is not fatal, but the subsequent DirectoryNotFoundException is.
