How to use same cert for 2 F5 environment

Find the below answer, If i understand properly.

Which SSL method should I create for this?

--> There are two types of SSL profile, Client SSL profile & Server SSL profile. Mostly we configure client-side SSL profile on VIP to secure connection between client machine to F5 BIGIP VIP.

Is it the "Creating an SSL CSR and private key" ?

--> Yes. Share CSR to third party(Verisign,GoDaddy, etc) to get certificate or generate self sign certificate.

I have F5 QA & F5 PROD, how can I use the same cert for both QA & PROD?

--> Archive Key & cert from One device and import to other device.

Paste if you have any other question..
