DNN 6.1.5 introduced the ability to use dashes in a page name. 

I've just run an upgrade on a site from 6.1.5 to 6.2.2. All the URLs have changed, the dash is gone.

6.1.5: www.example.com/test-page/ 

6.2.2: www.example.com/testpage

Does anyone know how I can fix this?

Do you around this?

I also needed dash in my page name but not able to find any  solution

I wanted to avoid any extension for this purpose and wanted to use whatever available in DNN

I am using DNN 6.2.4

I am simply adding page from Pagemanagement area and giving My Page Name as Test-Abc or Test_Abc

But it is stripping _ or - and making my page name in url as TestABc.aspx
