We have a Classic Partner Community that has Chatter Enabled and has a lot of posts over the past years. We are now trying to migrate our community to Lightning Template based Community (Customer Service template) and wondering if we can take the old posts and migrate them to the new community.
We have built the new Community but when you go to Chatter Feed, we only see the latest posts that we have in the new community.
Is there a way to migrate Chatter posts from the Classic Community into the new Community?
There is a lot of history there and we are not ready to part with it.
