Add a list to the root site for each site collection. Select the "Migration Notification URLs" list template (found under Blank & Custom list types)
You can name this whatever you like, but you should only have 1 of these lists at the site collection root because the tool uses the first one it finds
Here are some examples of the default notifications you can configure
You can also add your own custom notification messages
Here is the list configured at the Site Collection root level that defines your notifications
The new/edit item forms describe what should be entered in each field
Notification Tool Feature List
Site Collection Deployed full trust solution (Currently designed for SharePoint 2010+)
Client object model exclusively used for notification processing in order to support future releases on the SharePoint 2013 app model and Office 365 environments
Drop down selection of common notification scenarios
Migration notification list definition

Configurable notification text with wiki-like syntax for inserting hyperlinks or a date from the Migration Notification List
More Info URL

SharePoint client object model property bag caching to reduce server load and increase performance
Supports the standard notification color selections
Include all sub-sites (notification can be overridden at the child site level)
New / test site URL replacement including the full path to the current page/form
Notification disable flag
Automatic population of the title field from the New Site URL wiki when sent to a ".../NewForm.aspx?source=..." page (Using "New URL Set Title" syntax)
Permission based notification visibility (security trimming)
Added a MultiSelect choice field in the list called "Display To"
Automatically delete sites from the migration notification list by selecting Auto Delete or Auto Recycle in the Old Site Status field
This capability is enabled through a separate Site Collection feature and requires the user to have permissions to delete the site
This feature is especially useful for retention policies that require you to post a notice of deletion before deleting the site.
If you use Auto Delete instead of Auto Recycle, you should backup the site first if there is any possibility of needing a restore
