The links provided will sometimes have more information about Service Packs and support guidelines for a particular product.
Some more information on the Extended Support for Dynamics GP 10.0 can be found here.
You might also find this explanation of the Extended Support phase for Business and Developer products helpful.
Thanks Victoria, this is much easier to read that the support site. Am I reading your chart right that 9.0′s support ends in 2011?
We’re currently on 9.0 and are trying to figure out when the tax updates will end so we know when our drop – dead date is for upgrading.
Steven,
Yes, you are correct – GP 9.0 support ends on January 11, 2011. Not sure if this helps, but looks like there will be at least one more tax update for GP 9.0 based on information here: https://mbs.microsoft.com/customersource/downloads/taxupdates/usgptu9.htm?printpage=false.

I think that by extending the support to 10 years, MS is sending the message that they finally have they arms around the code base.
Darien,
I agree, I was surprised to see that extended support was available for GP 10.0. Another surprise is that this is not much announced – I would think this would be a huge selling point. Unless it’s so new that the marketing department just hasn’t caught up yet.

Finally a concise table listing it clearly!
Thank you Victoria!!!

Hi Victoria,
Thanks for posting this. I wasn’t aware of V10 having a lifecycle now of 10 years. I wonder when they decided to do that.
I also read from your link to the life cycle FAQ, that, “For Business and Developer products, Microsoft standardizes a minimum of 10 years of support.”
I’m more interested in the ‘why’ aspect of this as it seems new.
I’m guessing that it must be from feedback from customers OR to keep these products in line with the other Microsoft solutions.
Thanks again.

Victoria,
This is an excellent post! I will include as a stub on my blog.
