I built a new SP farm using intranet.domain.com for the host name and public URL of the main web app. We are migrating from 2007 to 2013. Unfortunately, intranet.domain.com is currently tied to our SP 2007 production environment. Our server team created a DNS named intranettest.domain.com for me to use until go live. Can I safely do the following without screwing up the sites content, permissions, and changes to the master page?:
Remove the web app from the IIS web site, leaving the "delete IIS web site" option as "no"
Extend the web app, using the existing app pool, and set the host
header and public url to intranettest.domain.com
Once we are ready to go live, the DNS entries will be updated to the new SP2013 IP addresses and I will have to change the web application back to intranet.domain.com
I did try AAMs but could not get them to work. I kept getting redirected to the IIS 8 web site. Not sure if I did something wrong though.
Any advice is appreciated!
