SHA2 Certificate Migration

I am currently in the process of migrating all of my managed SSL certificates from a SHA1 to a SHA2 signing algorithm. Based on other discussions, I'm still unclear on how I should be going about do...
certificate
sha256
ssl

A bit of clarification... I am running 11.2.1. I am only concerned about the key possibly being created in a way that does not fully support the sha2 signing algorithm. The F5 CSRs signing algorithm shows SHA1 when running certutil. However, the PKI (internal or third party) signs with SHA2 and the import works successfully with the correct algorithm. I'm only making sure to cover all bases.

 

Thanks!
