Symptom


When performing an in-place upgrade from Windows XP or Windows Vista RTM to Windows Vista Service Pack 1, the upgrade will take a long time to complete if files are present in the Offline Files cache. This can occur if the following is true:
  • Offline files is enabled on the client with a large number of files in the cache.
  • IPSec is enabled for network communication.
Cause
The in-place upgrade is performing an Offline Files migration which fails on each file processed. The process waits until the timeout is hit for each file represented.
Resolution


To workaround this problem perform the following steps:
  1. Synchronize the offline data using Sync Center or Sync button in Explorer.
  2. Disable offline files or disconnect the computer from the network. Disabling offline files is done by de-selecting Enable Offline Files from Folder Options, Offline Files tab.
  3. Perform upgrade.
