I'm working on 301 Redirect for all PHP pages in old website to redirect to the homepage of the new website.
For example: when user access to old link like (http://mysite.com/page.php?id=10), new Kentico website will automatically redirect to homepage (http://mysite.com/homepage).
How can I set up that in Kentico Admin or must do something else? Thanks.
I would look at using Url Rewrite module in IIS especially since you seem to want to redirect all PHP pages to your homepage. Have a look at http://www.iis.net/learn/extensions/url-rewrite-module/creating-rewrite-rules-for-the-url-rewrite-module
If all .php requests will go to the home page, then you can setup a redirect in IIS. If you want specific php pages to go to different new pages, this too can be setup in IIS although I'd suggest using URL Aliases for these as they can be managed within the CMS very easy.
