That is not a threat but a real must if you are using Feedburner to manage your blogs’ feeds. Feedburner was bought by Google back on 1st June 2007 and since then Google has decided to move every data and service to Google’s site. Now the final step remains and unfortunately, we have to make the move ourselves, now, before it’s too late!
If you don’t move now, here is your “reward”:
Unfortunately, Google Accounts will be required for all users to maintain feed management and monetization services at Google. We are currently planning to have all accounts transferred by February 28, 2009. At that time if your account has not been updated, you will no longer be able to access your account at http://www.feedburner.com, and your feeds will either begin returning a “404 Not Found” response or a “301 Moved” response back to your source feed. We encourage publishers who do not want to transfer their login to take their feed with them, using our 30-day redirect service, which will allow you to redirect your subscribers back to your source feed.
How to move your Feedburner to Google’s
Simply login to your Feedburner account at http://www.feedburner.com/fb/a/home and you should then see this message:
Click on the “Move your account now” to start moving your feeds. Then, simply follow the instructions to move all of your feeds to Google’s. It was quite easy and didn’t take much time for me.
When completed, you can now access your new Feedburner dashboard and services via http://feedburner.google.com (using your Google’s login id instead of your old Feedburner’s).
“Will something bad happen to my current subscribers count?”
Well here is the answer from the Big G:
You should not lose any readers of your feed during this transition process. All feeds.feedburner.com URLs will redirect your readers to feeds hosted by Google. Your readers will continue to receive your feeds. However, the reporting and analytics may take up to a week to adjust to internet traffic changes, so the number of subscribers you see in analytics reports may be lower for a short period of time.
After the transfer, it seems that Feedburner automatically redirects from my old feed URL (http://feeds.feedburner.com/MichaelAulia) to the new one (http://feeds2.feedburner.com/MichaelAulia) temporarily. So don’t forget to change all your template files (and posts) to reflect this change.
Also, my email subscription URL has changed from http://www.feedburner.com/fb/a/emailverifySubmit?feedId=1421883&loc=en_US to http://feedburner.google.com/fb/a/mailverify?uri=MichaelAulia&loc=en_US. Not to mention the email subscription form code has changed a bit too. So double check yours.
“Done them all? What’s Next?”
Test, Test, Test, and Test! Subscribe to your own feed and check if everything is alright. You don’t want to lose new potential readers because of a silly mistake that you make.
And *ahem*, don’t forget to subscribe to my feed too if you haven’t

Good luck in moving your account!

I moved my feed a couple of weeks ago. I lost half my subscribers virtually immediately. For the next couple of days the subscriber count kept going down. About 7 to 8 days later everything jumped back to normal. It does appear as if there is nothing to worry about, the initial inaccuracies are just temporary.
Hm..my feedburner counter is still stable but glad that it’s only temporary, even if it goes unstable
Thanks so much for this helpful post. I’d seen that AdSense had added another earning option of ads for your feeds, but didn’t know that moving the feeds from feedburner was a requirement. I’ve made the change and will now go update the email subscription links on my blog.
No problem. I haven’t added ads on my feeds though. I just thought that it may not be too popular with my subscribers heh heh
Mike, i had moved to google long time back. nice to see that you are alerting your readers…
I didn’t know we could move to Google long time ago… I feel left out
I read about this kind of warning a couple of weeks ago, but didn’t care less about it (i didn’t know the effect too), because i think why in the hell a company as large as google couldn’t just automatically moved feedburner account to google account.
after reading your post, i understand it’s pretty important to move it manually
but changing all of my template files (and posts) could be a pain in the *rse especially on my client and friends site that i help.
Thx for the head up
Well you should put the “subscribe to my blog” thingie on your template files, rather than the post files
This way, it’s easier to change
Fortunately, the transition from feedburner to Google was easy and I didn’t lose any subscriber count! But i don’t understand the reason behing moving the feeds. It still reads feeds2.feedburner.com/TechnicallyPersonal, huh?
I guess Google just wants to differentiate the service or server, perhaps? They don’t explain on the reason why
I have moved my feedburner account to Google a few months back.
I should have done it long time ago. Just didn’t realize that we could/needed to
The last time I checked ( about 4 weeks ago ), Google gave me an error message: We are unable to transfer your feeds now. And they promised they will correct the error.
Maybe time to try it again.
We had similar issues with subscriber #’s dropping on us immediately upon making the move. We did ours last week and we’ve experienced what a lot of people expressed here and on Twitter. Feed numbers all over the place. It does appear to be settling down. Thank gawd.
I guess if you have a fairly large number of subscribers, then you can notice the spikes
Google is really taking over the net huh. Well, I guess it will be intergrated into our Google accounts as one of their apps. They’re becoming the best virtual office with their Google accounts. You just have everything at your disposal.
