On-Premises Exchange 2013 to Office 365 Migration

What are the Common Bussiness challenges which are commonly faced when we migrate from On-Premises exchange to Office365. We are planning to do a Hybrid Migration where we have Exchange 2013 in Rackspace and we need to move it to Office 365. Also need to deploy Lync with Office365. Looking for the Bussiness chalenges and ways to overcome those challenges.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Business challenges will be different for every comapny. However below would be a few that I would think would be issues determining the circumstances...
- mailbox size (time it takes to move mail to the cloud)
- archiving on-prem solutions vs cloud
- retension policies
- cost/licensing
- administative control (you do lose some of this when you go with O365

Really you need to ask yourself, what am I going to benefit going with O365?

As for doing the actual migration i would be using something like Exchange Deployment Assistant to ensure that you have got a good high level plan in place to implement and execute a succesful migration.
