WordPress does not offer a core forum functionality as some other CMSs do, such as Drupal. Although so, it is possible to replicate forums using one of the available WordPress forum plug-ins, like the BBPress 2.x forum plug in, which is the one we strongly recommend. Although, other WordPress forum plug-ins could also be used, if desired. (Check with us the alternative you have in mind to see if it could work.)
Let us know if, apart from migrating the forum data, you would also like to redirect the URLs of all forum posts to the new WordPress forum. Redirection of URLs needs to be analyzed case by case, since forum modules / plugins usually follow a very free-form URL pattern that make it difficult their correct redirection.
