Previously, when I upgraded Open edX to the latest Teak version, I installed free certificates. However, the Teak version gave me some errors, and I wasn’t prepared for that, so I completely removed it and started upgrading again to the Sumac version. How can I apply the previously generated certificates for Teak, but now set them up for the Sumac version, so that during Docker builds I don’t have to manually specify them in the configurations each time?
