Recently one of my
clients who were using Office 365 SharePoint Online wanted to have a backup of
their sites in their on-premise SharePoint environment. I used a leading
SharePoint migration tool and was able to back up the sites to on premise
SharePoint. But when trying to open a site or a document library I ran into the
error “Could not load the assembly 'Microsoft.SharePoint,Version=16.0.0.0’”
The issue happened because Office 365 SharePoint Online is
has been updated to version 16 of SharePoint DLL while the on-premise SharePoint
2013 server had version 15 of the DLL. All the pages for sites, libraries and
lists were pointing to the version 16 of the DLL.
If it was single page a quick fix would have
been to open the page in SharePoint Designer and change the version of DLL to
15. But since there were many sites and sub sites with lots of libraries and
list I wrote a PowerShell script(courtesy http://www.sharepointdiary.com/2013/02/create-update-copy-delete-views-powershell.html)
to create new views for all lists and libraries and make them as default views.
As the new view pages are referencing version 15 of Sharepoint the sites and
libraries sprang back to life.
