The problem turned out to be that the "priceAuthority" object registered with the priceFeedRegistry was an ephemeral object that was not upgraded. This fixes that by re-registering the new priceAuthority. Then, to simplify the process of cleaning up the uncollected cycles reported in #9483, we switched to replacing the scaledPriceAuthorities rather than upgrading them. We also realized that we would need different coreEvals in different environments, since the Oracle addresses and particular assets vary for each (test and mainNet) chain environment. #9748 addressed some of the issues in the original coreEval. #9999 showed what was needed for upgrading priceFeeds, which was completed by #9827. #10021 added some details on replacing scaledPriceAuthorities. ### Security Considerations N/A ### Scaling Considerations Addresses one of our biggest scaling issues. ### Documentation Considerations N/A ### Testing Considerations Thorough testing in a3p, and our testnets. #9886 discusses some testing to ensure Oracles will work with the upgrade. ### Upgrade Considerations See above
