Hi @Abdulaziz ALHAKMANI ,
I noticed that we have interacted in another post, so here I have a question, are you looking for the steps of migrating Exchange2010 to 2016 in the "offline" state, or the steps of normal migration?
Normally, you could use the official Exchange deployment assistant tool, or you can also refer to this three-party blog series.
