SharePoint 2013 Content Database Attach/dettach:-

Hi,

I have two web applications in a Farm with following information:-

WebApplication-1

Associated Content Databases:-

ContentWA1DB1

ContentWA1DB2

===========================================

WebApplication-2

Associated Content Databases:-

ContentWA2DB1

ContentWA2DB2

Question:- Can i dismount content db's (ContentWA2DB1,ContentWA2DB2) from WebApplication-2 and attach them to Webapplication-1 in the same farm.I tried doing that in my dev farm but no one could access the sites after that.
