I have a customer who recently upgrade their AD from Windows server 2003 to 2008. The only remaining task , is to raise the forest and domain functional level to Windows 2008. My client wants to no PROS/CONS to raise domain and forest functional level but focus on their internal applications
Client wants to prepare a check list, or action items with the main things to check and validate that their applications are compatible with Windows 2008. I advised them to contact different vendors and prepare this checklist, but they want from a MS point of view, a second opinion or action plan;
What can be affected that applications stop working?
Where to look at server applications? code, databases, authentication methods, application type and so on?
Can you please enumerate main things to review for each application and validate that MS supports that?
Any known issues or gotchas when you migrate from 2003 to 2008 ?
Please, do not recommend to open an advisory case, I know that you guys have the expertise to provide as much information as you can on this regards
Please, I would like to read thoughts from different teams, AD, Windows server and Consulting teams
Thanks in advance
