Hello to all members as it is my first time here. I have an exchange 2010 sp3 installed on a VM with Windows 2008 R2 on it . I have to upgrade it to Exchange 2016 on another VM with Windows 2016 . As I am concerned for any possible interruption of users mail services , I would like to ask if there is an risk of stopping the mail services during the migration from Exchange 2010 to 2016 process. Thank you in advance
