Does creating a root site collection affect existent managed path site collections?

Question

In our existent sharepoint 2013 web we only have site collections in the default managed path http://servername/sites/collectionname. Is it safe to create a root site collection without affecting the existent collections, such as search or user permissions?

The only reason we want a root site is to use alias name (CNAME) to connect, and then redirect to one of the other collections.

Answer 1

Yes it's fine to create a root site collection. In fact in the past I've come across scenarios where not having a root site collection actually caused issues (though I can't remember off the top of my head what those issues were).

Answer 2

Simple HTTP Redirect in IIS should do the trick without having to add root site collection and do client side redirect.

Answer 3

You should create the Root Level Site collection, without root level Site collection SharePoint will have tons of Issue. Couple of these are

• MMS will have issue
• MySite will not work properly
• many Urls reside under the root site level( _layouts folder) will be broken

It is safe to create and you should do it.
