When upgrading DotNetNuke the typical method is to
- Backup your database and site
- Extract the Upgrade zip file into your root directory
- Open a browser
- Navigate to your site (http://domainname)
At this point the upgrade process begins and hopefully ends without error. However, once in a while you get a message like this one (sorry, I forgot to grab a screen shot)
XML Parsing Error: Syntax Error
Location: http://{your domain}/Install/UpgradeWizard.aspx
Line Number 1, Column 1:
404: Page not found (http://{your domain}/Install/UpgradeWizard.aspx)
I’ve looked everywhere and can’t find the solution, but I did find the work around. Follow this alternate upgrade path:
- Backup your database and site
- Extract the Upgrade zip file into your root directory
- Open a browser
- Navigate to http://{domainname}/install/install.aspx?mode=upgrade
That’s been working for me. If you have another solution please share in the comments.
