Copy-SPSite for /PWA doesn't work on SharePoint 2013

Question

Hello I'm trying to make a script to move an ProjectServer site from one farm to another. To to this, first I import the WSS_Content database then try to rename the /PWA site with Copy-SPSite powershell cmdlet. Then I mount the project server databases and do other work.

The problem is when I try to copy the /PWA site to /PWAExample it creates another / site that doesn't work. If I run Test-SPSite http://domain/ it gives me this huge error. The Copy-SPSite http://domain/sites/old -targetUrl http://domain/sites/new works. It dosent work with Copy-SPSite http://domain/PWA -targetUrl http://domain/PWAExample

Answer 1

The problem was that /PWA is actualy a managed path. And copy a site collection to new managed path you first have to create it with Explicit inclusion.
