Posting to Blog

I have been using Blogger to post to all the blogs here at church for years now. It's been great because their software already has the work put into it to archive old posts and keep the new ones in order and have links to them all and everything. Unfortunately, I just received notice that they are turning off that functionality for us in another month. Now I don't know what we're going to have to do but I'm looking around for software I can change to that will import everything that has been done over the years and allow us to move forward without a tremendous amount of work on my side. Any ideas?
