If you are moving to our platform and you wish to create 301 redirects so that you do not loose any SEO value we can do this for you without any problems.
What we need from your is a list that's in this same format below that contains your old URL's and new URL's.
RewriteRule ^OLDURLHERE$ NEWURLHERE [NC,L,R=301,O]
RewriteRule ^/homes-for-sale-in-toronto$ http://www.yourdomain.com/communities/toronto/ [NC,L,R=301,O]
RewriteRule ^/homes-for-sale-in-mississauga$ http://www.yourdomain.com/communities/mississauga/ [NC,L,R=301,O]
Once you put together that list email it to email@example.com and we will create all the redirects.
