Problem accessing archived items from OWA after upgrade

Hi all!

I have upgraded my EV 9 to EV 10.0.2 with external help.. Done this by installing new 2008R2 server and using export/import.

After this all Outlook client work fine but we cant access archived items from OWA Exchange 2007SP2 CAS/HUB NLB.

Been digging arround a bit and found that I cant find the EVAnon virtual site in IIS and alos found some missing IIS roles compared to the old 2008  EV server.

We deployd this night and still havent a full backup...is it safe to install the missing roles and run the OWAUSer.wsf to fix the OWA problem wihout any risk of the new/moved data?

have also run the EVORT att one CAS/HUB and got this..Failed Virtual Directory information could not be obtained.

Thanks in advance!
