Denali – Day 31: Discontinue and Breaking/Behavior change features

Discontinue Features:

As discussed about Deprecated will going to discontinue with that in Denali there are some features which has already discontinued. Means if you try to use those features they will not work in Denali. These featured were already in Deprecated list for earlier version for quite some time and hence finally it is discontinued.

Following are some of the features:

  • The major discontinue feature is Sql server 2000 (compatibility level 80), now with Denali you cannot work on sql server 2000 databases it has to be upgraded to at least 2005 (90) to be migrated to Denali.
  • VIA protocol is discontinued.
  • SQL Mail facility removed need to use outlook database mail
  • As most of the Windows OS is going to 64bit, and mostly in future there will be minimum of 64bit OS available. So possibility “no AWE” aware on 32bits, means memory would be more than 4 GB, and 32-bit Hot Add memory support.
