Keep old DC SEO links active - Possible?

I have installed DC SEO hack and want to upgrade to vbSEO.
Since I have lot of links within the forum posts (cross links added by users) using DC SEO rewrite rules I am afraid of loosing it.

Is there a way to keep them alive?
I have also 127000 pages indexed in Google, but I hope Google will rebuild it.

Thanks

Hello,

yes, you will be able to redirect old indexed link to a new URLs with rewrite rules added in .htaccess before the vBSEO's directives:

Code:

RewriteRules ^f([0-9]+)-.+\.html forumdisplay.php?f=$1
RewriteRule ^t([0-9]+)(-p([0-9]+))?.+\.html showthread.php?t=$1&page=$3
