I have a SharePoint 2013 server where the installation is corrupted. I have two sites, one of which works and the other one doesn't. I am able to access some areas of Central administration but not all. For example if I try to view Site Collections it says the page cannot load due to corruption.
I have built a new SharePoint 2013 server and I am wondering whether I should create a new farm and detach/attach the databases or whether I should join this new server to the existing farm and make the new server host the central admin site instead? - with my theory being that there would no longer be any corruption at least not on this server. Then once that done, move the site to the new server instead of using the old.
Thoughts?
