You hear about all the new features in SharePoint 2010, but what isn’t there? I bet you haven’t had many of those discussions yet. I think the news is better and I think the news is understandable. When you look through the methods in a list like this, it can sometimes look overwhelming, but compared to older versions, this is much much smaller than previous.
There are a few notes to help you understand the deprecation from a developer perspective first, and then will discuss the features in the product.
SPS2010NewlyDeprecated.txt – A fairly short list of depreciated types and methods no longer supported in SharePoint 2010.
SPS2010Deprecated.txt documentation, 528K, uploaded Oct 28 2009 – 573 downloads
OfficeSharePointServer2007Deprecated.txt – to understand the API types and methods that were first deprecated in SharePoint 2007 including recommendations on many of them
Depreciated Features to be aware of in SharePoint 2010:
1. Performance Point as a separate product – Now baked in/Included in SharePoint 2010 Enterprise.
2. My Site Host Redesign – No visual upgrade for my sites. The my sites really get a new look and feel… this is a good thing… really! Also be aware the Project Web Access as applicable doesn’t support visual upgrade (related to Project 2007 on SharePoint 2007 farm). I think most people didn’t customize this.
3. Side by Side Installation/Gradual Upgrade – No install of both binaries on the system, but you’ll be pleased that SharePoint 2010 ships with both 2007 and 2010 UI
4. SSP Admin UI – Any work you did on either the SSP Admin Site Collection or the Central Admin site has changed.
5. Central Admin – Admin task list and other lists that you might have created… You should move this to another site collection prior to upgrade.
6. Reporting Server webparts – New Design. Should work with an in place upgrade.
7. Deprecated Template – SSP Admin Site
8. Deprecated Template Great Plains (STSPKPL) – Template in 2003 plus pack. Use the Great Plains Integration Manager for richer SharePoint Integration with GP.
9. Features – PortalLayouts (Legacy)
10. Missing Assemblies – Web parts (STSPKPL) – This was also the case for 2003 to 2007. Shouldn’t be very common.
If you were at the SharePoint Conference, there was a session on Upgrading Code to SharePoint 2010 as well Sean Livingston mentioned some of this in his advanced upgrade
Let me know if I’m missing anything…
