Hello All,
I have Exchange Servers 2013 CU 13 in my environment and I have created a new website in the IIS to create new owa, ecp virtual directories to user login from internal and external networks. I am planning to upgrade to the Latest CU. As we all know that the new CU upgrade means installation of exchange from scratch. In my case do I have to re-create the new website again after I upgrade to the new CU or will the new website (owa and ecp virtual directories) be available even after the CU upgrade.
