We have an old (2009) Yammer network that uses an outdated SSO. In preparation for the change on 1 Dec, it looks like we might have to create a new Yammer tenant through our O365 environment and then merge the old one.
The problem as I understand it from our IT dept who has spoken to Microsoft is that we will actually lose all our content. Has anyone else encoutered this issue? It's really going to affect our adoption and trust if we lose all the conversations.
