Moved blog and lost everything

As you can probably tell, I have moved my blog to Blogger from serendipity. The reason for this is simply cohesion. All of my calendars, notes, well everything I do is managed from my gmail account, johnstout@acousticallyspeaking.net. I thought it would be better for me if everything were managed from that same google account. In the move I lost all of my previous posts. I am not sure why that happened. I was very careful to try to move everything just so but in the process the formatting between the two blog sites are not compatible and I lost previous posts. There was some good stuff in there too. I am going to spend a few hours this afternoon trying to locate and convert those files. wish me luck
