Upgrade 3.8.7 to 4.2.1 and seo friendly urls

[Janm]

Hi all,

I want to upgrade from 3.8.7. to 4.2.1 but I need all my urls to stay as they are.
I use vbseo at the moment.
When I upgrade will all urls's stay the same?

You should really check with vBSEO. I believe they should remain the same but only vBSEO can advise you of this. You would probably need the 4.2 version of their add on too.

Obviously if you stopped using vBSEO then yes they would change.
