I have a potential new client with 12 users that has an onsite domain controller and file server (Dell server running 2008). They are already with office 365 and use the exchange aspect. They are keen to know if they can loose the server completeley. They have 250GB on the server currently and would like to move the data to onecloud.
Can someone just lay out the pros and cons of keeping a server? Is it best practice to run an on premise DC for local security and authentication?
