Exchange 2013 SP1 with a 2 member DAG (active/passive) 2 copies of DB and 1 Exchange 2016 edge server. Every since SP1 install, every time exchange has an "update" installed, the transport queue poisons itself over and over. In order to fix the issue, i had to stop the transport service and rename the queue then start the transport service. Thats not my question though. I only want to give as much info as possible.
Like i stated, we only have SP1, no CU's. So we need to update to CU11. 2 Questions:
1) since we have SP1, we don't need to install CU4 then CU5 all the way to CU11, right?
2) following http://exchangeserverpro.com/exchange-2013-installing-cumulative-updates/ we should update the active member first then the passive member or the passive member first then the active?
