Install/Replace script and migrate profiles

I have a server (Centos Linux) hosting my website which is currently using vldpersonals script. I just purchased a datingscript which will replace for the vldpersonals. I am looking for an expert who is able to perform the installation, migrate everything from the vldpersonals. The instruction for installation and technical support are available/provided by the software company. The software company provides me a free installation, and only charges $70 for migration of profiles. However, they asked for FTP details, but I have not created FTP in my server. The current script is installed in the file manager of Webmin, it requires java to upload the files for an installation request. Your task is to help me install the script and migrate profiles, or create FTP details (move the current files to FTP) and make it available to install the new script. The next task is to fix the postfix. My current postfix version is 2.6.6. This version does not support per-domain outgoing IP addresses. Thus the outgoing email is not working now. If I updated to Postfix 2.7, it would solve the problem, but my server Centos 6.6 is unable to update the postfix 2.7. The Virtualmin provided a solution here (I tried it, but I failed, or I did not do it in a right way): [login to view URL] Any other solution to resolve this going email issue is welcome.
