We have subsites under our top-level site that are getting really big and I am trying to move them to their own site. I've created a new site collection and a contentDB. When I import the subsite over, It completes with no errors. When I try to view the site I receive the "Oops, something went wrong" page.
What I've done in powershell
Export-SPWeb http://root/subsite -Path \\shared\export\export.cmp
New-SPSite http://root/sites/newSite -OwnerAlias "Domain\User" -Name "New Site" -Template "STS#1" -ContentDatabase WSS_New_Site
Import-SPWeb http://root/sites/newSite -Path \\shared\export\export.cmp
UPDATE: I was able to get this moved over to a /sites/newSite path. The issue was that I did not have a feature enabled on the new site.
Now I'm trying to move it to its own managed path at
http://root/newSite so that it would look the same as it did originally. I followed the same step I completed to get it to work the first time, now getting the same unsuccessful results. The site creates fine and import gives no error, but the site won't load. I can get to the site settings page afterwards, but cannot make any setting changes. The exported site only uses lists and a summary link webpart from what I can tell.
Is there a way to export the features being used by a subsite? Doing a simple comparison and enabling the features individually has not yielded any positive results.
