asked on migrating exchange 2003 to Office365
First of all, I'm not familiar with Azure Office 365 and see if I can just for one step migration without downtime.
We have AD with forest and domain functional level 2003 and Exchange server 2003.
There are not many users for this small business, about 70 user mailboxes.
I have to suggest my boss which way is better to go either on-premise or Azure office 365.
For on-premise, as I researched, I have to go through two step upgrades for AD and exchange server, 2008 -> 2016.
Instead, is it possible just go directly from on-premise exchange 2003 to Office 365? If then, how does it work with our current AD? Do I still raise forest/domain functional level to 2012? I am trying to figure what is the damage during the upgrade because this business is 24 hour operation, have to minimize the downtime.

@Francois...you cannot update Exchange 2003 or 2007 for that matter directly to Exchange 2016. What would have to be done would be to do a migration to Exchange 2010, remove Exchange 2003 THEN migrate to Exchange 2016.
@Scott, thanks for the details. I didn't detailed the process of Exchange update but it was the idea.

MigrationWiz is also a really good third party tool we used often. You just have to know that this solution is not free, you'll have to pay per user you migrate.
I second what Todd says....I have done a few migrations using MigrationWiz for Exchange 2003 and it makes it easier than doing a double hop migration. You do have to pay per mailbox for MigrationWiz
