Weblogic out of support

We are currently planning a PeopleTools upgrade to version 8.58. Our current timeline will take us through the end of 2020 and we are planning to deploy into productions in 2021 Q1. With this timeline in mind we get to an issue with our current version of weblogic. We are on version 12.1.3.0.0 and this is the last supported version with PeopeTools 8.54 and we have support until Dec 31, 2020. Being out of support with weblogic and not getting security updates for that Q1 of 2021 is the concern we have.
Is anyone else in this situation and how were you able to mitigate the risk.
Thank you.
