In short, I'm having the same "problem" as this guy:
I'm writing, because it seemed that this required wordpress.com / jetpack support intervention to combine the blog ID's of the "old" and "new" blogs (they're really the same blog, just on a different host - I moved from GoDaddy to Page.ly).
Unlike the earlier post, I simply migrated my blog from GoDaddy to Page.ly. I noticed that Page.ly has stats that start from scratch.
The blogs I'm talking about are called (in JetPack):
1.000.000 Miles & Counting (this is the original version of the blog, hosted on GoDaddy)
Shades of Grey in a Binary World (this is the current version, same exact content migrated to Page.ly, then I changed the name)
Blog URL: http://davidbressler.com
JetPack version: Latest
WordPress Version: Latest
Can someone help please?
By the way, would be great if this didn't require intervention - and if someone could tell me how to solve this myself I'd be happy to do it.
