Hi @nrapoza
The End of Life is mostly an End of Support - meaning after 31st December 2024, CData will no longer offer technical support, updates, or fixes for v4.1.8 or other pre-v22 versions of DBAmp (v5.1.9 and earlier). After that date, v4.1.8 will not break immediately, so you will continue using it for some time. However, due to changes over time with the Salesforce API, older versions of DBamp will eventually break since they will be using an older version of the API. We are not able to predict when exactly that will be. You will need to change to the new version eventually.
The main issue is that old enough versions of DBAmp can't understand serial numbers that expire in 2025 or later. That would be versions 3.x.y, so as long as you are past that, you should be fine to keep using it into the new year until you can get fully moved over.
