Preparing for 365

Brett, I'd be happy to have a chat by phone about this and our experience. I'm in Sydney and have a very long background (back to 1982) with Federal government. We are implementing O365 now, having had on-prem SharePoint (2010 > 2013) since 2012 and working with O365/SPO since August 2016. We've had Yammer since 2012 as well, we did nothing to roll it out, it just grew by itself (with some light supervision and maintenance so it didn't get out of control).

From a collaboration point of view, the ATO is likely to be similar to us - lots of users on email and using network file shares (plus personal drives). This is a long legacy that's hard to break.

I'll assume you will want to move users off personal drives to ODfB, and off network file shares to SPO.

Depending on your current SP on-prem architecture and if it's been customised, you may need to take a different approach with SPO.

From a collaboration point of view, you may need to consider what users will naturally want to use, versus what they will find strange and counter-intuitive; Teams may fall into the latter category unless they have an internal chat system already. One approach might be to focus first on 'one for one' equivalent services (email to email, SP to SPO), and then start to extend the options as required.

Send me a message here if you'd like to chat by phone.
