Hello there,
I am writing this on behalf of our company and we are expert with custom work related to vBulletin and xenforo. We have been offering our services for more than 9 years and did hundreds of migrations.
Our Migration Process:
1. Our admins will clone your live website on our state of the art development servers system so our process does not disturbs the live traffic on your current site.
2. We will dry run migration process and will test if everything is transferred to Xenforo after the process.
3. You will be invited to verify the data on our test server and live forum won't be effected by our work.
4. Once you verifies that everything is good to go, we will take another backup of live site and will perform the same process on server by turning live site off this time.
5. With our extensive experience we will arrange this process in such a way that it will take less downtime.
6. After completion of live data transfer you will be given access to verify the stuff on live site again.
7. After testing you can approve the work is done and free support period starts.
NOTE: We are good with your time mentioned for downtime.
Question: Don't you need old url redirects to new same content urls? This step is very important for keeping your old or seo settings alive.
Cost: This migration including installation and setup of all your above points plus url redirects will cost you something around
$888.
Looking forward to hear from you soon.
Thanks,
