Renewal SSL of BI4.1 Launchpad

Dear Experts,

We need to renew our BI Launchpad SSL certificate as its going to expire soon, I have gone some of the discussion and that not explain how to renew, all the discussed based on new SSL installation.

So how will renew the SSL certificate? just need to do like fresh install or there is the renew process?

Here certificate is used from Vendor, so vendor will renew and send the certificate, after that what steps we need to do?

Platform:

BI4.1 SP02

Windows 2008,

Tomcat
