Windows 7 All Day Upgrade
There’s much to commend Windows 7 and our experiences with clean installs of the pre Beta, Beta and RTM releases have been mostly very positive, however, the one thing we haven’t tried yet is a Vista to Win7 upgrade.
If the reports now circulating the web are anything to go by, it’s not something we’ll be trying anytime soon. According to ars technica, reporting test results carried out by Microsoft, in a worst case scenario it could take more than 20 hours. The circumstances are not that unusual, either, it concerns a mid-range PC, with 40 applications and a drive containing 650Gb of data.
The tests covered a wide range of configurations and upgrade times varies from 100 minutes, on a high end PC with 20 applications and 70Gb of data to a 345 minutes on a heavily used (125Gb of data and 40 applications) low-end PC. Clean installations on most PCs typically took between 30 and 40 minutes, which chimes with our experiences, so the moral of this story is don’t upgrade unless you absolutely have to, and have plenty of time to spare.
