Has anyone tried migrating Exchange to the cloud WITHOUT updating to SP3 level, and how did it go?

Last Modified: 2019-02-22
We are about to migrate from Exchange 2010 on-prem, to Exchange Online.  We are reading that it is recommended to be at 2010 SP3 level before using the Exchange migration tool.  We are currently at 2010 SP2.  Two questions are

1) Has anyone tried migrating Exchange to the cloud WITHOUT updating to SP3 level, and how did it go?

2) For those who did update to SP3, how long did it take them - how long was the server down for?  We have a 200GB information store, so not too large.

Thanks for your help!

You are asking about downtime ,that means there is no availability. If the email requirement for business is critical then you should think of introducing new server and make DB redundant.
