I want to move a blog site to one level upper (https://portal/Site/Subsite/Blog ->https://portal/Site/Blog).
1. I have exported the Blog site to blog.cmp (with "Export full security and All Versions").
2. I create a site with blog template https://portal/Site/Blog .
3. I import the blog.cmp with following command:
Import-SPWeb -Identity https://portal/Site/Blog -Path[path] -IncludUserSecurity -UpdateVersions Overwrite -Force
All datas have been imported successful. But I find some stardard datas from template exsit always (e.g. catagory 1 , 2, 3). It is not so serious. I can delete those data. But I get almost every where double webparts: double post webpart, double comments webpart, double categories webpart in quicklauch, double blog tools .... my question is how can I import the site with overwrite the exsting site but not appent the data?
