yammer

At my current customer, we have a lot of domains and many of them have a free Yammer network. We are rolling out Office 365 and want to consolidate all the networks that we have into one enterprise network. With this wish we got two options, just consolidate all networks and tell the users that all the networks are consolidated into one network and that all the conversations are lost or you can try to find out for every network who uses it and create a backup of all the conversations before you consolidate.
