Upgrading from Exchange 2010 SP1 to SP2 - Do all servers need to be updated that night
I plan to install the Exchange 2010 SP2 from Exchange 2010 SP1. I am not sure how long the service pack takes to install, but do all servers need to be updated to SP2 for email to work? Can you have some still on SP1 and some on SP2? I wanted to plan around if my maintenance window is long enough to complete the install in one night.

Just to confirm - you are still unsupported. Exchange 2010 SP2 went end of life last week. Therefore you need to upgrade again to continue to get support and updates.

When performing the update, I would check another admin does not have a terminal session open. We did have to restart a few of the servers when the installer was performing the installation. The installation went clean after the restarts. One of the SP2 installs could not shutdown a service, after we killed the .exe the install continued. The only thing after the install some of the services did not automatically turn back on with one server. A restart cleaned up the issue. The other item that happened the SP2 turned back on the SSL required on the root of the IIS\CAS. After we uncheck on main root, the redirect to to SSL worked fine.
