From vRewrite - SEOed URLs for vBulletin to VBSEO URL's without to lose

Hello,
I suggest to my big friend to buy vBSEO for he's Commercial forum, I am the web manager for this forum and some time a go I've installed on it a vrewrite mod found on vb.org for vBulletin 3.5.x version.

I want to upgrade my friend's forum from 3.5.x to 3.6.x and next to 3.7.x and installing vBSEO, the question is (please see the structure URL on Lotto Italia Forum. La comunità del lotto e superenalotto. Il portale del lotto italiano - Powered by vBulletin) how to redirect Vrewrite Indexed URL's to the vBSEO URL without to lose them?

The urls look like default vBulletin urls

Only if clicks the link from forumhome
otherwise the links look like this
Forum Display: I Vostri pronostici Big Match - Lotto Italia Forum. La comunità del lotto e superenalotto. Il portale del lotto italiano
ShowThread: Esperto di cavalli ? - Lotto Italia Forum. La comunità del lotto e superenalotto. Il portale del lotto italiano

That is a nightmare situation on SEO bases. The site is full with duplicate contents After your purchase you can create a support ticket and ask for 301 redirect assistance from old url's to new ones.

Yes but the question is, the URL's need to be redirect one by one?
I believe yes in this specific case...

I want more clarity please, the mine is a big responsibility in this case, the forum is not mine, you excuse me but it is not sufficient this answer:

After your purchase you can create a support ticket and ask for 301 redirect assistance from old url's to new ones

if it is really simple things without vBulletin default URL's, I say to my friend to take the vBSEO license immediately after the release of vB 3.7.

Thanks

Hello,

since he has forum/thread IDs in URLs, it should be possible to maintain redirection with 2 rewrite rules for them.

Okie, thanks both Mert and Oleg.
Always great and fast support here
