I have some issues with one of my Exchange2013-servers and want to upgrade from CU4 to CU8 to see if this will correct the issues. 2 questions:
- Where can I find step-by-step documentation on how to perform the upgrade, including the necessary steps to prepare AD?
- I have found articles saying that any customizations on the servers will be lost, what kind of customizations could this be? I hope that all setup with connectors, URLs and so on is preserved during the upgrade?
The server with the issues is member of a DAG.
BR,
